17–19 June 1941: Jacqueline (“Jackie”) Cochran was the first woman to fly a bomber across the Atlantic Ocean when she ferried a Lockheed Hudson from Canada to Scotland. The airplane was a twin-engine Lockheed Model 414 Hudson Mk.V (LR), Royal Air Force identification AM790 (Lockheed serial number 414-2872).

Recognizing that the War would require all available pilots, the United Kingdom’s Lord Beaverbrook and the United States Army Air Forces Chief of Staff, Major General Henry Harley (“Hap”) Arnold, felt the need to demonstrate that civilian women could serve as pilots of military aircraft in non-combat situations. Jackie Cochran, a famous record-setting pilot, was selected for the assignment.

Cochran had previously served as a Flight Captain ¹ with the Royal Air Force Air Transport Auxiliary. After a period of six months, she had returned to the United States at the request of General Arnold, where she served on his staff.

For this ferry flight, Captain Edgar Grafton Carlisle, Jr.,² was assigned as her navigator. The Hudson also carried a radio operator, today only remembered as Coates. Royal Canadian Air Force authorities felt that Miss Cochran was not physically strong enough to operate the Hudson’s hand brakes. The arrangement between her and the R.C.A.F. was that she would be allowed to fly the bomber as First Officer, but that Captain Carlisle would make all takeoffs and landings.³

Cochran, Carlisle and Coates departed Montréal, Québec, at 1920 G.M.T., 17 June, en route to Gander, Newfoundland. They flew 931 statute miles (1498 kilometers) in 5 hours, 4 minutes before landing at 0024 G.M.T., 18 June, and remained there overnight.

The following evening, 18 June, at 1857 G.M.T., they took off to fly across the North Atlantic Ocean, a distance of 2,122 statute miles (3,415 kilometers).

In her autobiography, Cochran wrote:

     Flying the ocean at night didn’t mean much. We were above an overcast and hardly saw water. But just before daylight, we were heard or spotted by radar and suddenly through the darkness tracer bullets came up in front and around us. There was sudden consternation on board. Carlisle rushed up to me and the radio operator came running out of his compartment with his Very pistol. He opened a hatch and by firing a certain colored bullet gave the signal of the day but this really served no purpose because the light could not have been seen from the surface of the water anyway and the firing at us was probably coming from a German submarine or one of our own friendly ships. I thought maybe the pilots in the mass meeting in Montreal were right after all and the Germans were going to make a test case of me. Anyway, the tracer bullets stopped almost as soon as they started and no noticeable damage was done to the plane. After daylight, a hole opened up in the overcast and we saw a ship burning at sea, but could do nothing about it except to make a report by radio because we had no fuel to spare to enable us to go down and cruise around. Then we caught sight of the coast of Ireland in the distance and it kept creeping up on us and growing larger and larger and more friendly. From off the coast of Ireland to Prestwick, Scotland, was a tortuous air route. The route went one way and then another—without any real pattern—and the route was changed daily to make it difficult for enemy planes or submarines to intercept. At the end of twelve hours, we came to a stop on the runway. Carlisle, under the regulation, made the landing.

—The Stars at Noon, by Jacqueline Cochran, Little, Brown and Company, Boston and Toronto, 1954. Chapter VI, Pages 102–103

They arrived at Prestwick, Scotland, at 0605 G.M.T., 19 June, after a flight of 11 hours, 8 minutes.

Jackie Cochran would go on to form the Women Airforce Service Pilots (WASPs).

The image below shows the Hudson ferried by Jackie Cochran in service later in the War. It is painted in the Coastal Command camouflage scheme.

The Lockheed Hudson was a twin engine light bomber developed by Lockheed from its Model 14 Super Electra civil transport. Both types were designed by the legendary Clarence L. (“Kelly”) Johnson. The B-14L prototype made its first flight 10 December 1938 from the Union Air Terminal at Burbank, California. It was flown by two Royal Air Force officers, Squadron Leader James Addams and Squadron Leader Randle. The prototype (also identified as Model 214-40-01) was purchased by Great Britain and assigned the R.A.F. identification N7205.

The Hudson flown by Cochran, AM790, was an improved Model 414, Hudson Mk.V. This was identical to the earlier Mk.III, with the substitution of Pratt & Whitney R-1830-S3C4-G Twin Wasp engines. The bomber was flown by a single pilot, with a navigator/bombardier, radio operator and gunner.

The Hudson Mk.V was 44 feet 3⅞ inches (13.513 meters) long with a wingspan of 65 feet, 6 inches (19.964 meters) and height of 11 feet, 10 inches (3.607 meters). It had a maximum gross weight of 20,000 pounds (9,072 kilograms).

The Mk.V was equipped with two air-cooled, supercharged 1,829.4-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S3C4-G (R-1830-61) two-row fourteen-cylinder radial engines with a compression ratio of 6.7:1. These had a normal power rating of 1,100 horsepower at 2,550 r.p.m. to 6,200 feet (1,890 meters) and 1,000 horsepower at 2,550 r.p.m at 12,500 feet (3,810 meters). The takeoff/military power rating was 1,200 horsepower at 2,700 r.p.m. to 4,900 feet (1,494 meters) and 1,050 horsepower at 13,100 feet (3,993 meters). The engines turned three-bladed propellers though a 16:9 gear reduction. They were 5 feet, 3.48 inches (1.612 meters) long, 4 feet, 0.19 inches (1.224 meters) in diameter, and weighed 1,495 pounds (678 kilograms).

The Hudson had a cruise speed of 220 miles per hour (354 kilometers per hour, and maximum speed of 246 miles per hour (396 kilometers per hour) at 6,500 feet (1,981 meters). Its service ceiling was 25,000 feet (7,620 meters).

The Hudson was designed to carry four 250 pound (113 kologram) or six 100 pound (45 kilogram) bombs. It was armed with two forward-firing .303 Browning Machine Gun Mk.II mounted in the nose and operated by the pilot, with another two .303s on flexible mounts at the waist position, and 2 additional Mk.IIs in a power-operated Bolton Paul dorsal turret. Eight rockets could be carried under the wings.

409 Hudson Mark Vs were built. 207 of these were a long range variant, the Hudson Mk.V(LR).

During World War II, Hudson Mk.V(LR) AM790 served with No. 500 and No. 608 Squadrons, both units of the Coastal Command, Royal Air Force.

¹ An ATA Flight Captain was an equivalent rank to a Royal Air Force Squadron Leader.

² Edgar Grafton Carlisle, Jr., was born 17 October 1908, at Baltimore, Maryland, and was a citizen of the United States. He was the first of six children of Edgar Grafton Carlisle and Elizabeth Henderson Spafford Carlisle. A former resident of Swarthmore, Pennsylvania, Carlisle was a 1928 graduate of the University of Pennsylvania.

He entered the United States Army as an aviation cadet at Kelly Field, Bexar, Texas, earning his reserve officer’s commission and aviator’s wings in 1930. He served as a lieutenant in the 28th Division Aviation Unit, Pennsylvania National Guard and commanded the 103rd Photo Section.

Carlisle married the former Miss Lillian Matarose Baker at Narberth, Pennslyvania, 9 January 1933. They would have two children.

Carlisle entered the Royal Air Force Ferry Command in September 1940. To do so, he was required to resign his reserve commission in the United States Army. In the King’s New Year’s Honors List, 1 January 1942, Captain Edgar Grafton Carlisle, R.A.F.F.C., was invested an Officer of the Most Excellent Order of the British Empire (Honorary). The insignia of this honor was presented at Government House, 3 February 1942, by Lord Athlone, Governor General of the Dominion of Canada.

Following the War, Carlisle worked in the banking industry. He also taught Aerial Navigation at the University of Vermont.

Edgar Grafton Carlisle, Jr., O.B.E., died at Burlington, Vermont, 27 March 1994.

11 June 1971: Sheila Scott O.B.E. (née Sheila Christine Hopkins) departed Nairobi, Kenya, on her third solo around-the-world flight. On this flight she used a new airplane, a twin-engine Piper PA-23-250 Aztec D which she named Mythre. It carried United Kingdom registration G-AYTO. Scott used a NASA navigation and locator communication system to constantly relay her position to a Nimbus weather satellite, and from there to a ground station.

Sheila Scott planned to not only fly around the world, but to fly from the Equator, over the North Pole, and back to the Equator again. She flew her Aztec from London, England, to Nairobi, Kenya, where she began the Equator–North Pole–Equator portion of the flight.

Scott took off from Nairobi on 11 June 1971 and headed northward to Khartoum, Sudan; Bengazi, Libya; Malta; arriving back at London on 21 June. From there she continued to Bodø, Norway; Andøya, Norway; Station Nord, Greenland; across the North Pole on 28 June; then southward to Barrow, Alaska; arriving at Anchorage, Alaska, on 3 July; San Francisco, California, to Honolulu, Hawaii, on 11 July. She recrossed the Equator heading south to Canton Island. On 23 July, Mythre arrived at Nadi, Viti Levu, Fiji, and then flew on to Noumea, New Caledonia. After a stop at Townsville, Queensland, Scott arrived at Darwin, Northern Teritory, Australia, 1 August. From there she continued to Singapore; Madras, India; Karachi, Pakistan; Bahrain; Athens, Greece; and finally completed her journey at London on 4 August. The trip took 55 days.

During the circumnavigation, Sheila Scott set seven Fédération Aéronautique Internationale (FAI) World Records for Speed Over a Recognized Course: Andøya, Norway, to Station Nord, Greenland, 213.61 kilometers per hour (132.73 miles per hour) ¹; Nord to Barrow, Alaska, 183.73 km/h (114.16 mph) ²; San Francisco, California, to Honolulu, Hawaii, 236.56 km/h (146.99 mph) ³; Darwin, Northern Territory, Australia, to London, England, 160.19 km/h (99.54mph). ⁴ Three of these records remain current. ⁵

Ms. Scott’s airplane was a 1971 Piper 23-250 Aztec (“Aztec D”), serial number 27-4568. The airplane was assigned the United Kingdom registration G-AYTO on 3 March 1971. The Aztec D was a six-place twin-engine light airplane based on the earlier PA-23-235 Apache, with a larger cabin and more powerful engines. It was of all-metal construction and had retractable tricycle landing gear. The Aztec D is 31 feet, 2.625 inches (9.516 meters) long with a wingspan of 37 feet, 1.750 inches (11.322 meters) and overall height of 10 feet, 3.875 inches (3.146 meters). The wing has 5° dihedral. The Aztec D has an empty weight of 3,042 pounds (1,380 kilograms) and a gross weight of 5,200 pounds (2,359 kilograms).

The Aztec D is powered by two air-cooled, fuel-injected, 541.511-cubic-inch-displacement (8.874 liter) AVCO Lycoming IO-540-C4B5 6-cylinder, horizontally-opposed, direct-drive engines. The -C4B5 has a compression ratio of 8.5:1 and a Maximum Continuous Power/Takeoff rating of 250 horsepower at 2,575 r.p.m. It weighs 374 pounds (170 kilograms). The engines drive two-bladed Hartzell constant-speed propellers with a diameter of 6 feet, 2 inches (1.880 meters).

The PA-23-250 Aztec D has a maximum structural cruising speed (V_NO) of 172 knots (198 miles per hour/319 kilometers per hour) at 7,500 feet (2,286 meters) and maximum speed (V_NE) of 216 knots 249 miles per hour (400 kilometers per hour). The service ceiling is 19,800 feet (6,035 meters). With standard fuel capacity of 144 gallons (545 liters) the airplane’s range is 1,055 miles (1,698 kilometers). Mythre carried an auxiliary fuel tank in the passenger cabin.

After the around-the-world flight, Scott returned Mythre to the Piper Aircraft Company at Lock Haven, Pennsylvania, for overhaul. Following Tropical Storm Agnes in June 1972, the Piper factory was flooded to a depth of 16 feet (4.9 meters) and Scott’s airplane, along with many others and much of the tooling for aircraft manufacture, was destroyed.

The flight covered approximately 28,658 miles (46,121 kilometers) and took 189 actual flight hours over 33 days.

During her around-the-world flight, Shiela Scott set ten Fédération Aéronautique Internationale (FAI) World Records for Speed Over a Recognised Course: London to Rome, 258.13 kilometers per hour(160.40 miles per hour) (FAI Record File Numbers 4679, 4680); London to Auckland, 41.42 km/h (25.74 mph) #4660, 4661; London to Darwin, 45.67 km/h (28.38 mph) #4666, 4670; London to Fiji Islands, 34.60 km/h (21.50 mph) #4672; 4673; Lisbon to London, 244.00 km/h (151.62 mph) #4956, 4657.

For her accomplishments, Ms. Scott was awarded the Silver Medal of the Guild of Pilots; the Brabazon of Tara Award for 1965, 1966 and 1967; the Britannia Trophy of the Royal Aero Club of the United Kingdom, 1968; and the Harmon International Trophy for 1966 and 1970.

Italy gave her the title, Isabella d’Este. Sheila Scott was appointed an Officer of the Most Excellent Order of the British Empire in the New Years Honours List, 1 January 1968.

Sheila Scott flew around the world twice in Myth Too, and a third time in a twin-engine Piper Aztec, Mythre. The Fédération Aéronautique Internationale data base lists 75 records for speed over a recognized course set by Ms. Scott. 31 of these remain current.

In a 1969 interview, Ms. Scott said:

“. . . This must be why I enjoy being in the air alone. But in fact I never feel alone in the air because one has to work so hard and experience such extremes of emotion. The senses, for example, are all highly intensified. The sense of sight. . . when you look down, a pale pink becomes a deep rose; the seas really do look as though they have turquoise gashes in them. . . The sense of smell: . . . up there you can smell everything individually. The people of each country soon learned this on my world flight. It started at Damascus where they filled the plane full of jasmine. . . .”

Myth Too was built by the Piper Aircraft Corporation in 1966 and was registered N8893P. It was a PA-24-260B Comanche, an all-metal 4–6 place, single-engine, low-wing monoplane with retractable tricycle landing gear. It is flown by a single pilot and can carry three passengers, though an additional two seats can be mounted at the rear of the passenger cabin.

The airplane is 25 feet, 3-7/16 inches (7.707 meters) long with a wingspan of 35 feet, 11-¾ inches (10.967 meters) with an overall height of 7 feet, 5-11/16 inches (2.278 meters). Empty weight is 1,728 pounds (783.8 kilograms) and maximum gross weight is 3,100 pounds (1,406.1 kilograms).

The Comanche B is powered by an air-cooled, fuel-injected 541.511-cubic-inch-displacement (8.874 liter) Lycoming IO-540-D4A5 6-cylinder overhead valve (OHV) horizontally-opposed engine with a compression ration of 8.5:1, rated at 260 horsepower at 2,700 r.p.m., driving a two-bladed Hartzell constant speed propeller through direct drive. The IO-540-D4A5 weighs 384 pounds (174 kilograms).

Cruise speed is 185 miles per hour (297.7 kilometers per hour). The range is 1,225 miles (1,971.5 kilometers) and the service ceiling is 19,500 feet (5,943.6 meters).

15 May 1941: Having been delayed by weather until 7:40 p.m., Gloster Aircraft Co., Ltd., Chief Test Pilot Phillip Edward Gerald Sayer taxied into position on the long, hard-surfaced runway at RAF Cranwell, stood on the brakes and advanced the throttle. When the engine reached 16,000 r.p.m., Sayer released the brakes and the little airplane began to roll forward.

Acceleration was slow. Relying on the feel of the flight controls rather than a pre-calculated airspeed, Sayer lifted off after 600–700 yards (550–640 meters), at about 80 miles per hour (129 kilometers per hour). At 1,000 feet (305 meters), he retracted the landing gear and continued to climb at reduced r.p.m. He reached a maximum 240 miles per hour (386 kilometers per hour) Indicated Air Speed at 4,000 feet (1,219 meters).

Sayer landed after a 17-minute first flight.

The airplane was the Gloster-Whittle E.28/39, registration W4041/G, the first of two prototype fighters powered by a turbojet engine. (The “/G” in the registration indicates that, for security reasons, the airplane is at all times to be under guard when on the ground.) It was a single-seat, single-engine, low-wing monoplane of all-metal construction. The E.28/39 had retractable tricycle landing gear, one of the first fighter-type aircraft with that configuration.

The Gloster E.28/39 was 25 feet, 3 inches (6.696 meters) long with a wingspan of 29 feet, 0 inches (8.839 meters) and overall height of 9 feet, 3 inches (2.819 meters). It had a fuel tank of just 81 gallons (368 liters) capacity. The prototype’s takeoff weight was 3,341 pounds (1,515 kilograms).

W4041/G was powered by a single Power Jets, Ltd., Whittle Supercharger Type W.1. The turbojet used a single-stage, centrifugal-flow compressor, ten reverse-flow combustion chambers, and a single-stage axial-flow turbine. The turbine had 72 blades. The W.1 produced 860 pounds of thrust (3,825.47 Newtons) at 16,500 r.p.m., burning paraffin (kerosene).

The E.28/39 had a single large air intake at the nose. This split into two ducts which passed around each side of the the cockpit, following the inner contours of the fuselage, and then entered a plenum chamber. Intake air was compressed approximately 4:1 and passed to the combustion chambers. Fuel was mixed with this heated, compressed air, then ignited. Flame temperatures approached 600 °C. (1,112 °F.) This very hot, expanding gas flowed through spiral ducts to the turbine blades, causing the turbine disc to spin to a maximum 17,750 r.p.m., above 4,000 feet (1,219 meters).

The turbine drove the compressor at the front of the engine through a central drive shaft. The exhaust gas left the engine and passed through a straight pipe to the rear of the fuselage. The high velocity gas exiting the tail of the aircraft—thrust—resulted in the aircraft being propelled forward at a proportional velocity.

Because of limitations in materials technology, the Whittle W.1 had a limited service life of just ten hours. To keep the most time available for flight tests, early static and taxi tests of the Gloster prototype were made using an engine built from non-airworthy parts and spare components. This engine was designated W.1X.

Over the next thirteen days, Gerry Sayer made fourteen flights, totaling ten hours. The E.28/39 reached a maximum of 25,000 feet (7,620 meters) and 300 miles per hour (483 kilometers per hour). W4041/G was restricted to 2g maneuvers because of stress placed on the cast aluminum compressor case.

Gloster test pilots conducted three series of flight tests with W.4041/G. With Gloster test pilot John Grierson in the cockpit, on 24 June 1943, W4041/G climbed to 41,600 feet (12,680 meters) in 27 minutes, and reached an absolute maximum altitude of 42,170 feet (12,853 meters). This flight completed Gloster’s flight test program and the airplane was turned over to RAE Farnborough.

A second Gloster E.28/39 was built, W4046/G. Using an improved Whittle W.2/700 turbojet engine, the second prototype reached a maximum speed of 505 miles per hour (813 kilometers per hour) in level flight at 30,000 feet (9,144 meters)—0.74 Mach.

On 30 July 1943, W4046 was lost when its ailerons jammed at high altitude. The pilot bailed out and parachuted safely, but the prototype jet airplane was destroyed.

On 27 April 1946, Gloster-Whittle E.28/39 W4041/G was placed in the National Aeronautical Collection, Science Museum, South Kensington, 27 April 1946.

Chief Test Pilot Phillip Edward Gerald Sayer, Esq., was appointed an Officer of the Most Excellent Order of the British Empire (OBE) on the New Years Honours list, 30 December 1941. He was killed in flying accident 22 October 1942, probably the result of a mid-air collision.

24–27 April 1929: At 0937 GMT on the 24th, Squadron Leader Arthur Gordon Jones-Williams, M.C. and Bar, and Flight Lieutenant Norman Hugh Jenkins, O.B.E., D.F.C., D.S.M., both of the Royal Air Force, departed R.A.F. Cranwell, Lincolnshire, England, aboard the Fairey Long Range Monoplane, J9479. Their destination was Bangalore, in the Kingdom of Mysore, British Indian Empire. They were attempting a long distance flight record.

Their departure had been delayed for several days while waiting for favorable conditions for takeoff. It was decided to limit the Monoplane’s takeoff weight to 16,000 pounds (7,257.5 kilograms) and wait for at least a 10 mile per hour (16 kilometers per hour) headwind before attempting to takeoff.

After 16½ hours in flight, Jones-Williams and Jenkins were overhead Istanbul, and reached Baghdad 10½ hours later. After another 22 hours airborne they were overhead Karachi, Sindh, in the Bombay Presidency (now, Pakistan). With an estimated 6 hours fuel remaining they were unable to reach Bangalore and elected to land at Karachi while it was still daylight.

The duration of their flight was 50 hours, 37 minutes. They had flown a distance of 4,130 miles (6,646.6 kilometers) on their non-stop flight.

Arthur Gordon Jones-Williams (1888–1929) was a second lieutenant in the Welsh Regiment during World War I. He was transferred to the Royal Flying Corps as a fighter pilot. He shot down 11 enemy airplanes and was awarded the Military Cross, followed by a Bar (a second award). Jones-Williams was promoted from Flight Lieutenant to Squadron Leader in the list of New Years Honors, 1 January 1928.

Flight Lieutenant Norman Hugh Jenkins, DFC, DSM, Royal Air Force, was appointed an Officer of the Most Excellent Order of the British Empire, 3 June 1925.

The Fairey Long Range Monoplane was an experimental airplane designed and built in 1928 by Fairey Aviation Company, Ltd., at Hayes, Middlesex, England, for the Royal Air Force to investigate methods of increasing the range of airplanes. The agreed price was £15,000.

It was flown by two pilots and had a bed for crew rest. It was a high-wing monoplane with a wing built of wood and covered by fabric. The Monoplane was 48 feet, 6 inches (14.783 meters) long with a wingspan of 82 feet (24.994 meters) and height of 12 feet (3.658 meters). The maximum takeoff weight was 17,500 pounds (7,937.9 kilograms).

J9479 was powered by a water-cooled, normally-aspirated, 1,461.135-cubic-inch-displacement (23.944 liter) Napier Lion XIA (Special) dual-overhead-cam (DOHC) “Triple Four” or “broad arrow” (three banks of four cylinders with a common crankshaft), now generally referred to as a  W-12 engine. The cylinder banks were separated by 60° angles. The Lion XI had four valves per cylinder and a compression ratio of 6:1. It produced 530 horsepower at 2,350 r.p.m., and a maximum of 570 horsepower at 2,585 r.p.m. It was a geared engine with a 1.885:1 gear reduction. The Lion XI was 5 feet, 1 inch (1.549 meters) long, 3 feet, 6 inches (1.067 meters) wide and 3 feet, 3 inches (0.991 meters) high. The engine weighed 995 pounds (451 kilograms). The XIA (Special) was specially-tuned for the Fairey Long Range Monoplane, and had a slightly higher compression ratio.

The cruise speed was 110 miles per hour (177 kilometers per hour). The fuel tanks in the wings had a capacity of 1,043 Imperial gallons (1,252.6 U.S. gallons/4,741.6 liters).

Because of headwinds encountered, the April flight was short of the record. Another attempt was made, this time with a destination in South Africa. On 16 December 1929, however, J9479 crashed at Djibel Lit, south of Tunis, French Tunisia. The airplane was destroyed and both A.G. Jones-Williams and N.H. Jenkins were killed.

23 March 1948: During a 45-minute flight over Hatfield, Hertfordshire, England, the de Havilland Aircraft Company chief test pilot, Group Captain John Cunningham, D.S.O., flew a modified DH.100 Vampire F.1 fighter to a Fédération Aéronautique Internationale (FAI) World Record for Altitude of 18,119 meters (59,446 feet).¹ Cunningham broke the record set nearly ten years earlier by Colonel Mario Pezzi in a Caproni Ca.161 biplane.² (See This Day in Aviation, 22 October 1938)

The de Havilland DH.100 Vampire F.1 flown by Cunningham was the fifth production aircraft, TG/278. It was built by the English Electric Company at Preston, Lancashire, with final assembly at Samlesbury Aerodrome, and made its first flight in August 1945. It was intended as a prototype photo reconnaissance airplane. The cockpit was heated and pressurized for high altitude, and a metal canopy installed.

The photo reconnaissance project was dropped and TG/278 became a test bed for the de Havilland Engine Company Ghost 2 turbojet (Halford H.2), which produced 4,400 pounds of thrust (19.57 kilonewtons) at 10,000 r.p.m. The Vampire could take the Ghost engine to altitudes beyond the reach of the Avro Lancaster/Ghost test bed already in use. The airplane’s wing tips were each extended 4 feet (1.219 meters) to increase lift.

The aircraft was stripped of paint to reduce weight. Smaller batteries were used and placed in normal ballast locations. Special instrumentation and recording cine cameras were installed in the gun compartment, and ten cylinders of compressed air for breathing replaced the Vampire’s radio equipment. At takeoff, the Vampire carried 202 gallons (765 liters) of fuel, 40 gallons less than maximum, sufficient for only one hour of flight. The takeoff weight of TG/278 was 8,400 pounds (3,810 kilograms).

John Cunningham had previously flown TG/278 to a world record 799.644 kilometers per hour (496.876 miles per hour) over a 100 kilometer course at Lympne Airport, 31 August 1947.³

TG/278 continued as a test aircraft until it was damaged by an engine fire in October 1950. It was used as an instructional airframe at RAF Halton.

A standard Vampire F.1 was 9.370 meters (30 feet, 8.9 inches) long with a wingspan of 12.192 meters (40 feet, 0 inches) and overall height of 2.700 meters (8 feet, 10.3 inches). The fighter had an empty weight of 6,380 pounds (2,894 kilograms) and gross weight of 8,587 pounds (3,895 kilograms).

The basic Vampire F.1 was powered by a de Havilland-built Halford H.1B Goblin turbojet engine. This engine used a single-stage centrifugal-flow compressor and single-stage axial-flow turbine. It had a straight-through configuration rather than the reverse-flow of the Whittle turbojet from which it was derived. It produced 2,460 pounds of thrust (10.94 kilonewtons) at 9,500 r.p.m., and 3,000 pounds (13.34 kilonewtons) at 10,500 r.p.m. The Goblin weighed approximately 1,300 pounds (590 kilograms).

It had a maximum speed of 540 miles per hour (869 kilometers per hour), a service ceiling of 41,000 feet (12,497 meters) and range of 730 miles (1,175 kilometers).

The Vampire F.1 was armed with four 20 mm Hispano autocannon in the nose, with 150 rounds of ammunition per gun.

Group Captain John Cunningham C.B.E., D.S.O. and Two Bars, D.F.C. and Bar, A.E., D.L., F.R.Ae.S, was born 1917 and educated at Croydon. In 1935 he became an apprentice at De Havilland’s and also joined the Auxiliary Air Force, where he trained as a pilot. He was commissioned as a Pilot Officer, 7 May 1936, and was promoted to Flying Officer, 5 December 1937. Cunningham was called to active duty in August 1939, just before World War II began, and promoted to Flight Lieutenant, 12 March 1940.

While flying with No. 604 Squadron, Cunningham was awarded the Distinguished Flying Cross, 28 January 1941. He was appointed Acting Squadron Leader, Auxiliary Air Force, and was decorated with the Distinguished Service Order, 29 April 1941. The Gazette reported,

“This officer has continued to display the highest devotion to duty in night fighting operations. One night in April, 1941, he destroyed two enemy bombers during a single patrol and a week later destroyed  three enemy raiders during three different patrols. Squadron Leader Cunningham has now destroyed at least ten enemy aircraft and damaged a number of others. His courage and skill are an inspiration to all.”

—The London Gazette, 29 April 1941, Page 2445 at Column 1.

Acting Squadron Leader Cunningham’s promotion to Squadron Leader (Temporary) became official 10 June 1941. The King approved the award of a Bar to his Distinguished Flying Cross, 19 September 1941. Squadron Leader Cunningham took command of No. 604 Squadron 1 August 1946.

On 3 March 1944 Wing Commander Cunningham received a second Bar to his Distinguished Service Order. According to The Gazette,

“Within a recent period Wing Commander Cunningham has destroyed three more hostile aircraft and his last success on the night of 2nd January, 1944, brings his total victories to 20, all with the exception of one being obtained at night. He is a magnificent leader, whose exceptional ability and wide knowledge of every aspect of night flying has contributed in large measure to the high standard of operational efficiency of his squadron which has destroyed a very large number of enemy aircraft. His iron determination and unswerving devotion to duty have set an example beyond praise.”

—The London Gazette, 3 March 1944, Page 1059 at Column 1.

Promoted to Group Captain 3 July 1944, Cunningham was the highest scoring Royal Air Force night fighter pilot of World War II, credited with shooting down 20 enemy airplanes. He was responsible for the myth that eating carrots would improve night vision.

In addition to the medals awarded by the United Kingdom, he also held the United States Silver Star, and the Union of Soviet Socialist Republics Order of the patriotic War (1st Class).

Following the War, John Cunningham returned to de Havilland as a test pilot. After the death of Geoffrey Raoul de Havilland, Jr., in 1946, Cunningham became the de Havilland’s chief test pilot. He remained with the firm through a series of mergers, finally retiring in 1980.

Cunningham was appointed an Officer of the Most Excellent Order of the British Empire (O.B.E.) in 1951, and promoted to Commander of the Most Excellent Order of the British Empire (C.B.E.) in 1963. He relinquished his  Auxiliary Air Force commission 1 August 1967.

Group Captain John Cunningham C.B.E., D.S.O. and Two Bars, D.F.C. and Bar, A.E., D.L.,  died 21 July 2002 at the age of 84 years.

5 January 1959: At White Waltham, Berkshire, England, test pilots Ron Gellatly and Johnny Morton set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 100 Kilometers Without Payload, flying the prototype Fairey Rotodyne, XE521, to an average speed of 307.22 kilometers per hour (190.90 miles per hour)¹ over a course from White Waltham Aerodrome to Wickham, Radley Bottom, Kintbury, and back to White Waltham. The prototype was not a helicopter, but a compound gyroplane. Its record is for Class E (Rotorcraft), Sub-Class E-2 (Rotodyne).

The Fairey Rotodyne was a unique aircraft. Like a helicopter, it was capable of hovering and low-speed translating flight. The main rotor had both cyclic and collective pitch and provided roll and pitch control. Unlike a helicopter, though, thrust for forward flight was provided by two turboprop engines. Varying the propellers’ pitch provided yaw control for the aircraft until about 80 knots, when the twin rudders were sufficiently effective. As the Rotodyne accelerated in forward flight, the stub wing provided increasing lift and at about 60 knots, the main rotor tip jets were turned off. The main rotor continued to turn in autorotation, as in a gyrocopter.

Flight controls were similar to those of a helicopter, with a cyclic stick and collective lever with a twist throttle. The pedals, though, rather than controlling a tail rotor, varied the propeller blades’ pitch and rudder angle. The elevators were controlled by electric trim motors.

Helicopters’ maximum speed is limited by retreating blade stall. The Rotodyne’s stub wing provided 60% of lift in cruise flight, allowing the main rotor to operate with a lower blade angle of attack, delaying the onset of the stall. With propulsion provided by the turboprop engines rather than the main rotor, blade angle is further reduced. This allowed the Rotodyne to reach higher speeds in flight than a conventional helicopter.

Also, unlike a helicopter, the Rotodyne’s rotor was not driven by engines through a gear reduction transmission, reducing the aircraft’s weight and complexity. Drive was accomplished by tip-mounted high pressure jet engines (“tip jets”), fueled by compressed air supplied by the turboprop engines and turbine fuel. There is no torque effect, so an anti-torque rotor (tail rotor) is not required. The rotor mechanism is simplified because lead-lag hinges are not necessary.

XE521 made its first flight 6 November 1957 at White Waltham with Ron Gellatly and Johnny Morton in the cockpit.

The Rotodyne’s four-blade main rotor used symmetrical airfoils. It was 90 feet (27.432 meters) in diameter and the blade tip speed was 720 feet per second (219.5 meters per second). The blades had a chord of 2 feet, 3 inches (0.686 meters). The rotor blades were built of steel for strength, fatigue life and resistance to corrosion. The leading edge spar was machined from a 35 foot rolled steel billet and the rear spar was fabricated of layered stainless steel. The airfoil is shaped by pierced stainless steel ribs. The steel skin was a single sheet, joined at the trailing edge.

The wing span was 46 feet, 6 inches (14.173 meters). The engines and main landing gear were  carried in long nacelles mounted under the wing.

The Rotodyne’s fuselage was 58 feet, 8 inches (17.812 meters) long. The cabin has a length of 46 feet (14.021 meters) and is 8 feet (2.438 meters) wide and 6 feet (1.829 meters) high, providing space for 40 passengers or up to 9,000 pounds (4,082.3 kilograms of cargo. Clamshell doors at the aft end provided for cargo loading. Overall height of the aircraft was 22 feet, 2 inches (6.756 meters).

The Rotodyne was powered by two Napier & Son Eland NEl.3 turboprop engines with a maximum rated power of 2,805 shaft horsepower and 500 pounds of thrust at 12,500 r.p.m. for takeoff. Maximum continuous power was 2,180 shaft horsepower and 420 pounds of thrust. These engines drove four-bladed Rotol propellers with a diameter of 13 feet (3.962 meters). An auxilary compressor at the rear of the engine supplied compressed air for the main rotor tip-jets. Each engine supplied power to opposite pairs of of rotor blades at 250 °C. (482 °F.)

The prototype had an empty weight of 24,030 pounds (10,899.9 kilograms)

Squadron Leader Wilfred Ronald Gellatly, OBE AFC, RNZAF (Retired) was born in 1920. He joined the Royal New Zealand Air Force in 1940. During the last year of World War II, he commanded No. 243 Squadron, Royal Air Force.

Squadron Leader Gellatly attended the Empire Test Pilot School in 1950, and for the next four years was the helicopter flight commander at the Aeroplane and Armament Experimental Establishment at RAF Boscombe Down. In the New Year’s Honors, 1 January 1954, the squadron leader was awarded the Air Force Cross. He joined Fairey Aviation ,Ltd., as Chief Test Pilot. On 8 June 1963, Gellatly was awarded the Queen’s Commendation for Valuable Service in the Air.

After the merger with Westland Helicopters at Yeaovil in 1967, Gellatly remained with the company as chief test pilot. On 1 January 1970, Squadron Leader Gellatly was invested an Officer of the Most Excellent Order of the British Empire. He retired from Westland in 1976 after having made the first flight of five new helicopters, including the Lynx. He died in 1983 at the age of 62 years.

Lieutenant Commander John George Peter Morton, OBE, Royal Navy Fleet Air Arm, was born in Lancashire, 10 May 1925. At Age 17 he entered the Fleet Air Arm and was sent to the United States for flight training. He was assigned to fly the Chance Vought Corsair from the aircraft carrier HMS Colossus. (One of the airplanes he flew, Corsair KD431, is on display at the Fleet Air Arm Museum, Yeovilton.)

Johnny Morton served as a test pilot on Supermarine Seafire XVs following the war, and then flew the Seafire from HMS Theseus, and then Sea Furies Sea Hawks from HMS Centaur.

The Royal Navy assigned Johnny Morton to Fairey Aviation as a test pilot. On 14 June 1969, Senior Test Pilot Morton was awarded the Queen’s Commendation for Valuable Service in the Air.

Morton was the lead test pilot on the Westland Wasp and the naval variant of the Westland Lynx. He made the first flight of Lynx XX469, 25 May 1972. On 21 November, XX469 suffered a tail rotor failure and was damaged beyond repair. Johnny Morton and his copilot were slightly injured. He was also the first pilot to roll the Lynx.

On 1st January 1975, John Peter George Morton was appointed an Officer of the Most Excellent Order of the British Empire.

After retiring from Westland, Morton and his wife moved to New Zealand. Lieutenant Commander John George Peter Morton OBE, died there, 4 May 2014, at the age of 88 years.

3 December 1945: The first landing and takeoff aboard an aircraft carrier by a jet-powered aircraft were made by Lieutenant-Commander Eric Melrose Brown, M.B.E., D.S.C., R.N.V.R., Chief Naval Test Pilot at RAE Farnborough, while flying a de Havilland DH.100 Sea Vampire Mk.10, LZ551/G. The ship was the Royal Navy Colossus-class light aircraft carrier, HMS Ocean (R68), under the command of Captain Casper John, R.N.

For his actions in these tests, Lieutenant-Commander Brown was invested an Officer of the Most Excellent Order of the British Empire (O.B.E.), 19 February 1946.

LZ551 was the second of three prototype DH.100 Vampires, which first flew 17 March 1944. The airplane was used for flight testing and then in 1945, was modified for operation for carriers. It was named “Sea Vampire” and reclassified as Mk.10.

The DH.100 was a single-seat, single-engine fighter powered by a turbojet engine. The twin tail boom configuration of the airplane was intended to allow a short exhaust tract for the engine, reducing power loss in the early jet engines available at the time.

LZ551/G was originally powered by a Halford H.1 turbojet which produced 2,300 pounds of thrust (10.231 kilonewtons) at 9,300 r.p.m. This engine was produced by de Havilland and named Goblin.

The Vampire entered service with the Royal Air Force in 1945 and remained a front-line fighter until 1953. 3,268 DH.100s were built. There were two prototype Sea Vampires (including LZ551) followed by 18 production Sea Vampire FB.5 fighter bombers and 73 Sea Vampire T.22 two-place trainers.

LZ551 is in the collection of the Fleet Air Arm Museum, Yeovilton, Somerset.

HMS Ocean was built at the Alexander Stephen and Sons yard on the Clyde, Glasgow, Scotland. The ship was launched in 1944 and commissioned 8 August 1945. Classed as a light fleet carrier, HMS Ocean was 630 feet (192 meters) long at the water line, with a beam of 80 feet, 1 inch (24.41 meters) and standard draft of 18 feet, 6 inches (5.64 meters) at 13,190 tons displacement; 23 feet, 3 inches (7.09 meters), at full load displacement (18,000 tons). The aircraft carrier’s  flight deck was 695 feet, 6 inches (212.0 meters) long. Ocean was driven by four Parsons geared steam turbines producing 40,000 shaft horsepower, and had a maximum speed of 25 knots (28.8 miles per hour/46.3 kilometers per hour). HMS Ocean had a crew of 1,050 sailors, and could carry 52 aircraft.

HMS Ocean served for twelve years before being placed in reserve. Five years later, she was scrapped at Faslane, Scotland.

Captain Eric Melrose Brown, C.B.E., D.S.C., A.F.C., KCVSA, Ph.D., Hon. F.R.Ae.S., R.N., is one of aviation’s greatest test pilots. He was born at Leith, Scotland, 21 January 1918, the son of Robert John Brown and Euphemia Melrose Brown. His father, a Royal Air Force officer, took him for his first flight at the age of 8. He was educated at the Royal High School, Edinburgh, Scotland; Fettes College; and at the University of Edinburgh. He received a Master of Arts degree from the university in 1947.

Eric Brown volunteered for the Royal Navy Fleet Air Arm, 4 December 1939. Having previously learned to fly at the University Air Squadron, Brown was sent to a Flying Refresher Course at RNAS Sydenham, Belfast, Northern Ireland.

Brown received a commission as a temporary Sub-Lieutenant, Royal Navy Volunteer Reserve, 26 November 1940. He briefly served with No. 801 Squadron before being transferred to No. 802 Squadron. He flew the Grumman G-36A Martlet Mk.I (the export version of the U.S. Navy F4F-3 Wildcat fighter) from the escort carrier HMS Audacity (D10) on Gibraltar convoys.

Having shot down several enemy aircraft, including two Focke-Wulf Fw 200 Condor four-engine patrol bombers, Brown was awarded the Distinguished Service Cross. HMS Audacity was sunk by enemy submarines in the Atlantic, 21 December 1941. Brown was one of only 24 to escape from the sinking ship, but only he and one other survived long enough in the frigid water to be rescued.

Sub-Lieutenant Brown met Miss Evelyn Jean Margaret Macrory on 7 April 1940. They married in 1942 and would have one son.

Brown was promoted to lieutenant, 1 April 1943. After a number of operational assignments, Lieutenant Brown was assigned to the Naval Test Squadron at the Aeroplane and Armament Experimental Establishment, Boscombe Down, in December 1943. The following month Brown was named Chief Naval Test Pilot at the Royal Aircraft Establishment, Farnborough. He held that post until 1949.

In July 1945, Eric Brown was promoted to the rank of lieutenant-commander (temporary), and then, following the war, he was transferred from the Royal Navy Volunteer Reserve to the Royal Navy, and appointed a lieutenant with date of rank to 1 April 1943.

Lieutenant Brown was awarded the King’s Commendation for Valuable Service in the Air in the New Year’s Honours List, 1949. Brown returned to No. 802 Squadron during the Korean War, flying from the aircraft  carriers HMS Vengeance (R71) and HMS Indomitable (92). He was promoted to lieutenant-commander, 1 April 1951. In September 1951, Brown resumed flight testing as an exchange officer at the U.S. Naval Air Test Center, Patuxent River, Maryland.

In 1953, Lieutenant-Commander Brown was a ship’s officer aboard HMS Rocket (H92), an anti-submarine frigate. He was promoted to commander, 31 December 1953. After a helicopter refresher course, Brown commanded a Search-and-Rescue (SAR) helicopter flight aboard HMS Illustrious. He next commanded No. 804 Squadron based at RNAS Lossiemouth, then went on to command RNAS Brawdy at Pembrokeshire, Wales.

From 1958 to 1960, Commander Brown was the head of the British Naval Air Mission to Germany. He then held several senior positions in air defense within the Ministry of Defence. He was promoted to captain 31 December 1960.

From 1964 to 1967, Brown was the Naval Attache at Bonn, Germany. He next commanded RNAS Lossiemouth, 1967–1970.

Captain Brown’s final military assignment was as Aide-de-camp to Her Majesty, Queen Elizabeth II of Great Britain.

Eric M. Brown was invested a Member of the Most Excellent Order of the British Empire (M.B.E.), 3 July 1945, for landings of a de Havilland DH.98 Mosquito aboard HMS Indefatigable, 2 May 1944. On 1 January 1970, Captain Brown was named a Commander of the Most Excellent Order of the British Empire (C.B.E.) in the Queen’s New Years Honours List.

Captain Eric Melrose Brown, C.B.E., D.S.C., A.F.C., K.C.V.S.A., Ph.D. Hon. F.R.Ae.S., R.N., retired from active duty 12 March 1970.

At that time, he had accumulated more than 18,000 flight hours, with over 8,000 hours as a test pilot. Captain Brown had flown 487 different aircraft types (not variants), a record which is unlikely to ever be broken. Brown made more landings on aircraft carriers than any other pilot, with 2407 landings, fixed wing, and 212 landings, helicopter. He made 2,721 catapult launches, both at sea and on land.

In 1982 and 1983, Captain Brown served as president of the Royal Aeronautical Society.

Eric “Winkle” Brown died at Redhill, Surrey, England, 21 February 2016, at the age of 97 years.

17 November 1954: Lionel Peter Twiss, Chief Test Pilot for Fairey Aviation Company Ltd., was flying the company’s experimental supersonic airplane, the Fairey Delta 2, WG774, from the aircraft test center at RAF Boscombe Down, Salisbury, Wiltshire, England. This was the FD.2’s fourteenth flight.

When about 30 miles (48 kilometers) from the airfield and climbing through 30,000 feet (9,144 meters), the airplane’s fuel supply was interrupted and the engine flamed out.

Unwilling to lose a valuable research aircraft, Twiss decided to stay with the Delta 2 rather than ejecting, and he glided back to Boscombe Down, descending through a layer of cloud at 2,500 feet (762 meters). Without the engine running, the aircraft had insufficient hydraulic pressure to completely lower the landing gear and only the nosewheel strut locked in place. The FD.2 touched down at 170 miles per hour (274 kilometers per hour) and was seriously damaged.

WG774 was out of service for nearly a year. The wings had to be replaced and those which had originally been built for structural tests were used.

For his effort to save a valuable research aircraft, Peter Twiss was awarded the Queen’s Commendation for Valuable Service in the Air. Notice of the award was published in The London Gazette, 22 February 1955, at Page 1094:

Lionel Peter Twiss, Test Pilot, Fairey Aviation Company Ltd. (Hillingdon, Middlesex.)

     For services when an aircraft, undergoing tests, sustained damage in the air.

On 10 March 1956, Peter Twiss flew WG774 to set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15km/25km Straight Course at an average speed over a 9-mile course, flown between Chichester and Portsmouth at and altitude of 38,000 feet (11,582 meters). Two runs over the course were made, with first averaging 1,117 miles per hour (1,798 kilometers per hour) and the second, in the opposite direction, was 1,147 miles per hour. (1,846 kilometers per hour). The FD.2 had averaged 1,822 Kilometers per hour (1,132 miles per hour)—Mach 1.731. ¹

Twiss had broken the previous record of 1,323.312 kilometers per hour (822.268 miles per hour) which had been set by Colonel Horace A. Hanes, U.S.Air Force, flying a North American Aviation F-100C Super Sabre over Edwards Air Force Base, California. ²

Peter Twiss was the first British pilot, and the FD.2 the first British airplane, to exceed 1,000 miles per hour (1,609 kilometers per hour) in level flight. Twiss is also the last British pilot to have held a World Absolute Speed Record.

For his services as a test pilot, Lieutenant-Commander Lionel Peter Twiss, D.F.C. and Bar, was appointed Officer of the Most Excellent Order of the British Empire, 13 June 1957.

The Fairey Aviation Company, Ltd., Delta 2 WG774 (c/n F9421) is the first of two single-place, single-engine delta-wing research aircraft which had been designed and built to investigate transonic and supersonic speeds. It first flew 6 October 1953 with Chief Test Pilot Peter Twiss in the cockpit.

In its original configuration, the FD.2 is 51 feet, 7½ inches (15.735 meters) long with a wingspan of 26 feet, 10 inches (8.179 meters) and overall height of 11 feet (3.353 meters). The wings’ leading edge were swept to 59.9° with an angle of incidence of +1.5°. Ailerons and flaps were at the trailing edge and acted in place of elevators. In its original configuration it had an empty weight of approximately 11,000 pounds (4,990 kilograms) and the all-up weight at takeoff was 14,109 pounds (6,400 kilograms).

The FD.2 was powered by a Rolls-Royce Avon RA.28R afterburning turbojet engine which produced 9,530 pounds of thrust (42.392 kilonewtons), or 11,820 pounds (52.578 kilonewtons) with afterburner (“reheat”). This was a single-shaft axial-flow turbojet with a 15-stage compressor and 2-stage turbine. The RA.28 was 10 feet, 3.0 inches (3.124 meters) long, 3 feet, 5.5 inches (1.054 meters) in diameter, and weighed 2,869 pounds (1,301 kilograms).

WG774 and its sistership, WG777, were used for flight testing throughout the 1960s. WG774 was modified as a test aircraft to study various features of the planned British Aerospace Concorde. The landing gear struts were lengthened and the fuselage extended by six feet. It received a “drooped” nose section for improved pilot visibility during takeoff and landings. New wings were installed which had an ogee-curved leading edge. With these modifications WG774 was redesignated BAC 221. In this configuration, WG774 was tested to Mach 1.65 at 40,000 feet (12,192 meters).

WG774 was retired in the early 1970s. It is on display at the Fleet Air Arm Museum, Yeovilton, Somerset, England.

Peter Lionel Winterton Twiss ³ was born 23 July 1921 at Lindfield, Sussex, England. He was the son of Colonel Dudley Cyril Twiss, M.C., a British Army officer, and Laura Georgina Chapman Twiss. Peter was educated at the Sherborne School, a prestigious boarding school for boys, in Dorset.

Twiss briefly worked as a tea taster for Brooke Bond & Company, but in 1939 enlisted as a Naval Airman, 2nd class, Royal Navy Volunteer Reserve. He trained at HMS St Vincent, a training school for the Fleet Air Arm at Gosport, Hampshire. He was appointed a Temporary Mishipman (Probationary), 26 August 1940. He was assigned to 771 Squadron, 27 January 1941, and was trained as a fighter pilot. Midshipman Twiss was commissioned as a Temporary Sub-Lieutenant (A), 23 July 1942.

Twiss was variously assigned to HMS Sparrowhawk, a Naval Air Station in the Orkney Islands, where he flew target tugs for gunnery training; HMS Daedalus, at Lee-on-Solent, Hampshire, England; and HMS Saker, a Royal Navy accounting base located in the United States.

Temporary Sub-Lieutenant (A) Lionel Peter Twiss, R.N.V.R., was assigned as the pilot of a Hawker Hurricane Mk.I with the Merchant Ship Fighter Unit. (Hurricanes could be launched by catapult from merchant ships to defend against Luftwaffe Focke-Wulf Fw 200 Condor reconnaissance bombers.)

He next flew the Fairey Fulmar fighter with No. 807 Squadron from HMS Argus (I49), in support of Malta in the Mediterranean Sea. Sub-Lieutenant Twiss is credited with shooting down one enemy fighter and damaging a bomber. He was awarded the Distinguished Service Cross, 22 September 1942. He and his squadron transitioned to the Supermarine Seafire aboard HMS Furious (47) and were in action during the invasion of North Africa. He was awarded a Bar, denoting a second award, to his D.S.C., 16 March 1943.

Sub-Lieutenant Twiss, D.S.C. and Bar, was promoted to the rank of Temporary Lieutenant, 17 August 1943. After returning to England, Twiss was trained as a night fighter pilot. He flew the de Havilland DH.98 Mosquito with an RAF night fighter unit on intruder missions over France. In 1944 he shot down two more enemy airplanes.

Later in 1944, Twiss was sent to the United States to work with the British Air Commission. In this position, he was able to fly various U.S. fighter aircraft, including the turbojet-powered Bell P-59 Airacomet.

Lieutenant-Commander Twiss was in the third class of the Empire Test Pilots’ School and after graduation he was assigned to Fairey Aviation for duty as a test pilot.

With the end of World War II, Lieutenant-Commander Twiss left the Royal Navy and continued working as a civilian test pilot at Fairey. He became to the company’s chief test pilot in 1954.

For his record-setting flight, in 1956 Twiss was awarded The Segrave Trophy of the Royal Automobile Club.

7 November 1945: Wing Commander Hugh Joseph Wilson, A.F.C. and Two Bars, Royal Air Force, Commandant of the Empire Test Pilots’ School at RAF Cranfield, set the first world speed record with a jet-propelled airplane, and the first speed record by an airplane in excess of 600 miles per hour (965.606 kilometers per hour), when he flew the Gloster Meteor F Mk.IV, EE454, to 975.68 kilometers per hour (606.26 miles per hour)—0.80 Mach—at an altitude of 75 meters (246) above Sea Level.

The course was an 8 mile (12.9 kilometers) straight away from the Herne Bay Pier to Reculver Point, along the south coast of the Thames Estuary. This was a new Fédération Aéronautique Internationale (FAI) record for speed over a 3 kilometer course. ¹

Months of preparation by both the Royal Air Force, which formed a special “flight,” and Gloster Aviation Co., Ltd., went into the speed record effort. Two Meteor F Mk.III fighters, EE454 and EE455, were modified to the new Mk.IV version to attempt the speed record.

The standard B.37 Rolls-Royce Derwent Series I turbojet engines were replaced with Derwent Series V turbojets and lengthened jet nacelles. The wings were shortened, the tips reshaped and the canopy was cut down and strengthened. All trim tabs on flight control surfaces were disabled and their edges sealed. Landing gear and gear door up-latches were strengthened to prevent them from being sucked open at high speed. The airplanes were lightened and all armament deleted. The surfaces were smoothed and painted in a gloss finish. EE454 retained the standard camouflage pattern, while EE455 was painted in a distinctive yellow-gold color.

Many hours of flight testing were performed to ensure that the airplanes would be stable enough at high speeds while flying at the very low altitude required by the Fédération Aéronautique Internationale‘s rules. The slightest deviation from smooth flight could have disastrous results.

EE454 was flown by Wing Commander Hugh Joseph Wilson, A.F.C. and Two Bars (three awards), and EE455 by Gloster Chief Test Pilot Eric Stanley Greenwood. Each airplane was required to make four passes over the 3 kilometer (1.8641 statute miles) course, with two runs in each direction. The airplanes were required to remain at or below 75 meters (246 feet) during the runs over the course, and during the turns at the end of each run, below 400 meters  (1,312 feet).

On the day of the speed runs, the weather was marginal. It was cold and overcast, and visibility varied from 7 to 12 miles 11–19 kilometers) along the course. The wind was 8–12 miles per hour (3.6–5.4 meters per second) from the northwest.

Wilson made four passes over the course. His speeds for each run were 604, 608, 602 and 611 miles per hour (972, 978, 969, and 983 kilometers per hour). Greenwood made his speed runs an hour later. His runs were 599, 608, 598 and 607 miles per hour (964, 978, 962 and 977 kilometers per hour).

Wilson’s average speed was the higher of the two. His official FAI-homologated record speed is 975.68 kilometers per hour (606.26 miles per hour). Greenwood’s average speed was 970.63 kilometers per hour (603.122 miles per hour.).² Both pilots are credited with official FAI world speed records.

Post-flight inspections revealed that the sheet metal of the Meteors’ engine intakes had significantly distorted by the intense pressure differentials experienced during the speed runs.

The B.37 Rolls-Royce Derwent Series V, interestingly, was not a direct development of the preceding Derwent Series I–IV engines. Instead, it was a scaled-down version of the RB.41 Nene, which was in turn, a scaled-up and improved Derwent I. The Derwent V had a single-stage, two-sided, centrifugal-flow compressor and a single-stage axial-flow turbine. The compressor impeller and turbine rotor were mounted on a single shaft which was supported on each end by roller bearings, and in the center by a ball bearing. The Derwent V used nine combustion chambers, and burned aviation kerosene. Engine lubricating oil was added to the fuel at a 1:100 ratio, by volume. The Series V had a Normal Power rating of 3,000 pounds of thrust (13.345 kilonewtons) at 14,000 r.p.m., and a Take-off or Military Power rating of 3,500 pounds of thrust (15.569 kilonewtons) at 14,600 r.p.m. (There was no time limit for this power setting.) The engine produced a maximum 4,000 pounds of thrust (17.793 kilonewtons) at 15,000 r.p.m. at Sea Level. During the speed runs, thrust was restricted to 3,600 pounds (16.014 kilonewtons) on both Meteors. The Derwent V engine was 7 feet, 4.5 inches (2.248 meters) long, 3 feet, 7 inches (1.092 meters) in diameter and weighed 1,280 pounds (581 kilograms).

(Rolls-Royce named its piston aircraft engines after predatory birds, e.g., Kestrel, Merlin, but its turbine engines were named after rivers.)

He qualified in flying boats and acted as a flight instructor for the RAF Reserve School. Wilson was promoted to Flight Lieutenant 1 April 1937, with seniority retroactive to 1 April 1936.

While a reserve officer, Wilson was a test pilot for Blackburn Aircraft Ltd., and made the first flight of the Blackburn Roc. He then became a civil test pilot at the Royal Aircraft Establishment, Farnborough.

In 1939 Flight Lieutenant Wilson was recalled to active duty. He was assigned as Commanding Officer, Aerodynamic Flight, RAE Farnborough, and also flew with No. 74 Fighter Squadron at Biggin Hill. On 1 September 1940, Wilson was promoted to the rank of Squadron Leader. In 1941, Wilson was appointed chief test pilot at the Royal Aircraft Establishment and was responsible for testing all captured enemy aircraft. He was promoted to Wing Commander, 20 August 1945.

Wing Commander Hugh Joseph Wilson, A.F.C. and Two Bars, Royal Air Force, was named Commander of the Most Excellent Order of the British Empire (C.B.E.) in the King’s Birthday Honours List, 13 June 1946.
