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.
26 September 1927: Flight Lieutenant Sidney Norman Webster, A.F.C., of the Royal Air Force High-Speed Flight, won the 1927 Schneider Trophy Race, flying a Supermarine S.5 float plane, number N220.
The course consisted of seven laps of a 50-kilometer course at Venice, Italy. Webster completed the race in 46 minutes, 20.3 seconds, averaging 281.656 miles per hour (453.281 kilometers per hour). He established a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over 100 Kilometers.¹
Webster’s teammate, Flight Lieutenant Oswald Worsley, flying S.5 N219, placed second with a time of 47:46.7 and average speed of 272.91 miles per hour (439.21 kilometers per hour).
The Supermarine S.5 was designed by Reginald Mitchell, who would later design the famous Supermarine Spitfire fighter. N220 was a single-place, single-engine, low-wing monoplane equipped with pontoons for landing and taking off on water. The airplane was of all metal construction, primarily duralumin (a hardened alloy of aluminum and copper). The airplane used surface radiators in the skin of the wings for engine cooling.
The S.5 had a length of 24 feet, 3½ inches (7.404 meters), wingspan of 26 feet, 9 inches (8.153 meters) and height of 11 feet, 1 inch (3.378 meters). The S.5’s empty weight was 2,680 pounds (1,216 kilograms) and gross weight was 3,242 pounds (1,471 kiograms).
Webster’s Supermarine S.5 was powered by a water-cooled, naturally-aspirated 1,461.135-cubic-inch-displacement (23.943 liter) D. Napier and Son, Ltd., Lion Mk.VIIB, serial number 63106, a double-overhead camshaft (DOHC) twelve-cylinder engine with three banks of four cylinders. This was called a “Triple-Four,” “W-12,” or “broad arrow” configuration. The Napier Lion had an included angle of 60° between each cylinder bank.
The Mk.VIIB had four valves per cylinder and a compression ratio of 10:1. It produced 875 horsepower at 3,300 r.p.m. The Lion VIIB drove a two-bladed fixed-pitch propeller through a gear reduction unit with a ratio of 0.765:1. (Worsley’s Supermarine S.5, N219, was equipped with a 900 horsepower direct-drive Mk.VIIA.) The engine used a mixture of 75% gasoline, 25% benzol, and 0.22% “T.E.L. dope” (tetraethyl lead) additive. The Napier Lion Mk.VII was 5 feet, 6¼ inches (1.683 meters) long, 3 feet, 2½ inches (0.978 meters) wide and 2 feet, 10½ inches (0.876 meters) high. The geared Mk.VIIB was heavier than the direct drive Mk.VIIA, and weighed 920 pounds (417 kilograms).
The Supermarine S.5 had a maximum speed of 319.57 miles per hour (514.3 kilometers per hour).
“Webbie” Webster had been awarded the Air Force Cross on 2 January 1922. He received a second award, signified by a “bar” added the the ribbon of his medal, 11 October 1927:
11th October, 1927.
The KING has been graciously pleased to approve the award of a Bar to the Air Force Cross held by Flight Lieutenant Sidney Norman Webster, A.F.C., in recognition of his achievement winning the recent “Schneider Cup” Air Race.
In January 1946, Air Commodore Webster was appointed Commander of the Most Excellent Order of the British Empire. He was promoted to Air Vice Marshal in 1949 and retired from the Royal Air Force 12 August 1950.
Air Vice Marshal Sidney Norman Webster, C.B.E., A.F.C. and Bar, Royal Air Force, died 5 April 1984 at the age of 83 years.
28 August 1957: Michael Randrup, Chief Test Pilot of D. Napier and Son, Ltd., and Walter Shirley, Deputy Chief Engineer, fly this Royal Air Force/English Electric Canberra B Mk.2, WK163, to an altitude of 21,430 meters (70,308 feet) over southern England. This set a new Fédération Aéronautique Internationale (FAI) World Record for altitude.¹
The Canberra was being used to test Napier’s Double Scorpion NSc D1-2 rocket engine, which was used to drive the airplane far beyond its normal service ceiling of 48,000 feet (14,630 meters).
After taking off from Luton, Bedfordshire, at 5:26 p.m., Mike Randrup used the Canberra’s two 6,500-pounds-thrust (28.91 kilonewtons) Rolls-Royce Avon RA.3 Mk. 101 turbojet engines to climb to 44,000 feet (13,411 meters), where he throttled the engines back to cruising r.p.m. and then ignited the Double Scorpion. The Canberra climbed at a very steep angle until reaching the peak altitude.
At this high altitude, there is an extremely narrow margin between the airplane’s stall speed and it’s critical Mach number—the point at which supersonic shock waves start to form on the wings and fuselage. On an Airspeed Limitations Chart, this area is known as “Coffin Corner.” Aerodynamicists had calculated that Randrup needed to keep the Canberra within a 15-knot range of airspeed.
Though the Canberra’s cockpit was pressurized, both Mike Randrup and Walter Shirley wore pressure suits in case of emergency.
WK163 landed back at Luton at 6:12 p.m.
In 1958, the Royal Aero Club of Great Britain awarded the Britannia Trophy to Randrup and Shirley.
The English Electric Canberra B.2 was the first production variant of a twin-engine, turbojet powered light bomber. The bomber was operated by a pilot, navigator and bombardier. It was designed to operate at very high altitudes. The Canberra B.2 was 65 feet, 6 inches (19.964 meters) long with a wingspan of 64 feet, 0 inches (19.507 meters) and height of 15 feet, 7 inches (4.750 meters). The wing used a symmetrical airfoil and had 2° angle of incidence. The inner wing had 2° dihedral, and the outer wing, 4° 21′. The total wing area was 960 square feet (89.2 square meters). The variable-incidence tail plane ad 10° dihedral. The airplane’s maximum takeoff weight was 46,000 pounds ( kilograms).
The Canberra B.2 was powered by two Rolls-Royce Avon RA.3 Mk. 101 engines. The RA.3 was a single-spool axial-flow turbojet with a 12-stage compressor section and single-stage turbine. It was rated at 6,500-pounds-thrust (28.91 kilonewtons).
The B.2 had a maximum speed of 450 knots (518 miles per hour/833 kilometers per hour). It was restricted to a maximum 0.75 Mach from Sea Level to 15,000 feet (4,572 meters), and 0.79 Mach from 15,000 to 25,000 feet (7.620 meters). Above that altitude the speed was not restricted, but pilots were warned that they could expect compressibility effects at 0.82 Mach or higher.
The Canberra was produced in bomber, intruder, photo reconnaissance, electronic countermeasures and trainer variants by English Electric, Handley Page, A.V. Roe, and Short Brothers and Harland. In the United States, a licensed version, the B-57A Canberra, was built by the Glenn L. Martin Company. The various versions were operated by nearly 20 nations. The Canberra was the United Kingdom’s only jet-powered bomber for four years. The last one in RAF service, a Canberra PR.9, made its final flight on 28 July 2008.
WK163 was built under license by A.V. Roe at Woodford, Cheshire, in 1954, and accepted by the Royal Air Force 28 January 1955. Having spent its entire career as a research test bed, WK163 was declared surplus in 1994 and sold at auction to Classic Air Projects Ltd. It was assigned civil registration G-BVWC.
G-BVWC last flew in 2007. As of December 2016, the record-setting Canberra was undergoing a full restoration at Robin Hood Airport, near Doncaster, South Yorkshire.
Michael Randrup was born in Moscow, Imperial Russia, 20 April 1913. He was one of four children of Søren Revsgaard Randrup and Alexandra Pyatkova Randrup. He held Danish citizenship through his father, who had emigrated to Russia in 1899. Following the Russian revolution, the Randrup family relocated to England.
Michael was educated at The King’s School in Canterbury, Kent. He became interested in aviation in his early teens, and took his first flight as a passenger aboard an Avro 504K biplane. He began flight lessons at Bekesbourne Aerodrome in 1935, and soloed in June 1936. Randrup applied to join the Royal Air Force but was turned down because of his Danish citizenship. He then went to the Automobile Engineering College in Chelsea, West London, to study aeronautical engineering.
Randrup graduated in 1939, and along with a cousin, Ivan Christian Randrup, formed a small air charter company, AllFlights Ltd., at Heston Aerodrome, west of London. They operated a de Havilland DH.85 Leopard Moth, de Havilland DH.90 Dragonfly, and a Heston Type I Phoenix II (G-AEYX). The Phoenix was impressed into service by the R.A.F., 5 March 1940.
World War II bought their fledgling company to a close. (Ivan Randrup briefly flew for B.O.A.C. before going on to the Air Transport Auxiliary. First Officer Randrup died 29 January 1941.)
After Denmark fell to Nazi Germany in April 1940, Michael Randrup was accepted by the R.A.F. He received a commission as a Pilot Officer on probation, Royal Air Force Volunteer Reserve, 4 September 1940. One year later he was promoted to Flying Officer.
On completion of his military flight training, Pilot Officer Randrup was sent to a flying instructors school. For the next two years, he served as a military flight instructor in England and Southern Rhodesia. In 1942, Flying Officer Randrup was transferred from Training Command to Fighter Command and on 6 October, was assigned to No. 234 Squadron, then stationed at RAF Perranporth, flying the Supermarine Spitfire Vc. A number of Danish pilots had been assigned to No. 234. On 1 January 1943, Randrup was seconded to Air Service Training, Ltd., at Hamble, just southeast of Southampton, where he flight-tested new-production, repaired and overhauled Spitfire fighters.
In 1944, Randrup was assigned as a test pilot at the Royal Aircraft Establishment at Farnborough. Among other assignments, he flight-tested a captured Heinkel He 177 A-5/R-6 twin-engine heavy bomber. In 1945, Randrup was appointed Officer Commanding, Engine Research and Development Flight. By the end of the war, he had been promoted to the rank of Squadron Leader.
Following the war, Randrup went to work for D. Napier and Son Ltd. In 1946, he became the company’s Chief Test Pilot. The following year, he became a naturalized subject of the United Kingdom and the British Empire.
From 1966 until 1973, Randrup served as manager for the British Aircraft Corporation in Saudi Arabia. BAC provided aircraft and missiles to the Royal Saudi Air Force.
Michael Randrup was twice married, first to Florence May Dryden, and then to Betty Perry. They would have two children.
Michael Randrup died in February 1984 at the age of 70 years.
Walter Shirley was educated at the Blackpool Grammar School, a private boarding school in Blackpool, Lancashire, and St. Catherine’s College, University of Cambridge.
Shirley was employed as a scientific officer at RAE Farnborough from 1942 to 1946. It was while there that he first flew as a flight test engineer with Squadron Leader Randrup. Shirley was sent to an R.A.F. flight school for pilot training. In 1946, he was assigned to rocket engine development.
Shirley joined Napier in 1947, working on turbine engines. In 1952, he was appointed Chief Technician. In 1956, Shirley was made the Chief Development Engineer for the Scorpion engine. He later became the company’s Deputy Chief Engineer.
22 August 1922: Captain Stanley Cockerell, A.F.C., a test pilot for Vickers Ltd (Aviation Department), made the first flight of the prototype Type 56 Victoria Mk.I, J6869, at Brooklands, Surrey, England.
The Victoria was a twin-engine biplane military transport, developed from the earlier Vickers Vernon and Virginia. It was operated by a crew of two in an open cockpit and could carry up to 22 troops.
The prototype Vickers Victoria was powered by two water-cooled, normally-aspirated, 1,461.135 cubic-inch-displacement (23.944 liters) D. Napier and Son Ltd. Lion I, a 60° “triple Four” or “broad-arrow” 12-cylinder engine (also known as a W-12), rated at 450 horsepower at 1,925 r.p.m., each. This was a very complex engine, using individually machined steel cylinders surrounded by welded stamped-steel water jackets. The cylinders were closed at the upper end, rather than having a separate cylinder head. Four valve ports were machined into the “crown.” Each cylinder had two intake and two exhaust valves, which were operated by a dual overhead camshaft arrangement. The cylinders were screwed into a aluminum “head block” which provided stiffening to the assembly, and contained intake and exhaust runners and cooling passages. The three individual banks of four cylinders were attached to the crankcase by studs. The engine’s crankshaft used large roller main bearings for support. The engine used a dry sump lubrication system with an oil pick up at each end. The propeller was driven through a 2:1 reduction gear unit. Cast aluminum alloy pistons were fitted to a master rod with two side rods. The Napier Lion was was compact, very light for the power it produced, and also very efficient. The Napier Lion I weighed approximately 860 pounds (390 kilograms).
The Vickers Victoria had a maximum speed of 110 miles per hour (177 kilometers per hour), and a service ceiling of 16,200 feet (4,940 meters). Its range was 770 miles (1,240 kilometers).
97 Victoria transports were built by Vickers. The type remained in service with the Royal Air Force until 1935 and saw extensive use in Iraq and Afghanistan.
Stanley Cockerell had been an aircraft mechanic before becoming a fighter pilot. On 27 October 1916, Serjt. Cockerell was assigned to the Royal Flying Corps. He was credited with seven aerial victories during World War I, while flying the Airco DH.2, DH.5 and the Sopwith Camel.
Albert I, King of the Belgians, conferred the Chevalier de l’Ordre de la Couronne to Temporary 2nd Lieutenant Cockerell, 21 September 1917. On 25 October 1917, Cockerell was promoted to the temporary rank of Captain. He was awarded the Belgian Croix de Guerre 11 March 1918.
For a flight from England to South Africa in a Vickers Vimy, 24 January–26 February 1920, (“The Times Flight”) Captain Cockerell was awarded the Air Force Cross by George V.
On 4 June 1921, Flight Lieutenant Stanley Cockerell, A.F.C., Royal Air Force, was transferred to the unemployed list.
In 1921, Cockerell married Miss Lorna Lockyer. They would have seven children.
In 1922, Cockerell competed in the King’s Cup, a cross country air race, flying a Vicker’s Type 61 Vulcan, G-EBEM. He finished in 7th place. In the 1923 race, he flew a Type 74 Vulcan, but that airplane did not finish.
Stanley Cockerell and his six-year-old daughter, Kathleen, were killed during the Battle of Britain, when the Luftwaffe bombed Sunbury-on-Thames, 29 November 1940. Mrs. Cockerell was also killed during The Blitz.
