29 August 1955: Wing Commander Walter Frame Gibb, D.S.O., D.F.C., a test pilot for the Bristol Aeroplane Co., set a new Fédération Aéronautique Internationale (FAI) world record for altitude when he flew an English Electric Canberra B Mk.II, WD952, to 20,083 meters (65,889 feet), near Filton, Gloucestershire.¹
A brief notice in Flight:
At 3 p.m. last Monday, Bristol assistant chief test pilot Walter Gibb took off from Filton in the Olympus-Canberra in which, during May 1953, he established a world’s height record of 63,668 feet. The Canberra, which has since been fitted with two Olympus 102 BOI.11 turbojets, was airborne for one hour. Gibb’s purpose was to better his own record and, accordingly, G/C du Boulay and Mr. Philip Mayne, of the Royal Aero Club, were in attendance. Personnel of the R.A.E. were engaged in calibration, but as we go to press it was unlikely that the outcome would be known before the end of next week.
—FLIGHT and Aircraft Engineer, No. 2432, Vol. 68, Friday, 2 September 1955 at Page 338, Column 1
The Telegraph reported:
. . . taking off from Filton, he climbed over the Bristol Channel towards Ireland and levelled off at 50,000 ft in order to burn off fuel to lighten the aircraft before continuing his ascent.
He turned east and finally reached a new record altitude of 65,876 ff (nearly 12.5 miles high) over Bristol. Gibb, who was flying solo, observed: “The last 500 ft took an awfully long time. It was the most difficult flying I have ever experienced.”
WD952 was equipped with the new Bristol Olympus BOI.11 Mk.102 engines. The Olympus was a two-spool axial-flow turbojet which produced 12,000 pounds of thrust (53.38 kilonewtons).

This was the second FAI altitude record set by Gibb with WD952. Two years earlier, 4 May 1953, Gibb had flown the Canberra to an altitude of 19,406 meters (63,668 feet).²
On 9 April 1956, WD952 was taking off from Filton when the left engine suffered a turbine blade failure at 50 feet (15 meters). In the resulting forced landing, the Canberra’s left wing struck an oak tree and was torn off. The record-setting airplane was damaged beyond repair and was scrapped.
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.

29 August 1938: At 7:37 a.m., Alexander Nikolaevich Prokofiev-Seversky departed Floyd Bennett Field, Brooklyn, New York, flying a Seversky AP-7 Pursuit, NX1384, an all-metal monocoque monoplane of his own design and manufacture, enroute to the Lockheed Air Terminal, Burbank, California, a distance of 2,457 miles (3,954 kilometers). He completed the flight in 10 hours, 2 minutes, 55.7 seconds, setting a new speed record for an East-to-West Transcontinental Flight. Major Seversky refueled during a 30-minute stop at Kansas City.
Larry Therkelson of the National Aeronautic Association was the official timer for the record attempt.

The Los Angeles Times reported:
SEVERSKY SETS RECORD
Flies across Country in Few Minutes More than Ten Hours
Maj. Alexander P. (Sascha) de Seversky, who flew fighting planes for the Czar of Russia and now builds pursuit ships for the American Army, yesterday notched another hour off the already incredibly narrow time-space separating the Atlantic and Pacific coasts.
In a “civilianized” fighter made at his Long Island factory, de Seversky thrashed along the 2600-mile airway from Floyd Bennett Field, N.Y., to Union Air Terminal, Burbank, in ten hours, three minutes, seven seconds, better than 260 miles per hour.
START AND FINISH
He had gobbled a husky breakfast of oatmeal, orange juice and toast in Manhattan as dawn arose over the skyscrapers (at 3:37 a.m. P.S.T.)
Under a blazing Southland sun that shot the mercury to 100 deg. at Burbank, he toyed with a chicken sandwich fifteen minutes after he set his pursuiter’s trim wheels down at exactly 1:40:07 p.m.
De Seversky was greeted—warmly—by Jacqueline Cochran, America’s No. 1 woman speed flyer for whom he was ferrying the all-metal monoplane to Los Angeles. She will retrace his course in the small hours of Saturday, seeking the lion’s share of the $30,000 Bendix Trophy purse.
It was, he said, “Practically nothing.”
TIME WASTED
In a new age of aeronautics, when pilots break records just in the day’s work during routine assignments, de Seversky stands with the best of ’em.
His time and speed would have been materially bettered if he’d been “trying,” he admitted. At Kansas City, plopping down into TWA’s hangars for refueling, he wasted a precious twenty-nine minutes while mechanics tinkered with his tricky gasoline system.
“Once I was traveling more than 300 miles an hour,” De Seversky admitted.
MERELY A WARM-UP
How much faster he could have flown, the esrtwhile White Russian declined to say—”Wait until ‘Jacky’ starts for Cleveland in the Bendix race,” he interposed.
“I used oxygen part of the way, especially when I climbed to 16,000 over the Kansas prairies during a hailstorm,” he said. “This whole flight was nothing but a warm-up. I could have flown nonstop. Instead, I tried different wing loadings and paused at Kansas City. Sometimes I throttled down to less than 240 miles an hour.”
Two hundred and forty!
Between bites of chicken sandwich, De Seversky pointed out that his 1200-horsepower plane can soar 3000 miles without refilling its wing-to-wing tanks that carry 540 gallons of high octane fuel. That, he observed, carries huge military significance.
“We are learning in the Army,” this builder of the nation’s fastest pursuit ships declared, “that bombardment craft are vulnerable to attack from the air unless properly convoyed.

Record Upset by Seversky
Continued from First Page
So—the ‘flying fortress’ that cruises 5000 miles must be accompanied by pursuit ships that can go equally as far nonstop. To Europe from America, for example.
THREE UNDER WAY
“In the United States at least three such planes are underway today. I am building one. Others may be twin-engined—such as the ship being readied at the Lockheed plant—and capable of terrific speeds.”
By Christmas of this year, de Seversky promised, a standard military fighter, soon to be released to Air Corps testers, will crack the long-sought-after 400-miles-an-hour mark.
BENDIX MARK SEEN
De Seversky was cool as he braked his craft to a halt under the gaze of Larry Therkelson, official National Aeronautic Association timer. He removed his earphones, slipped out of his jumper and asked, “When’s lunch?” To statements that he had knocked Roscoe Turner’s five-year-old record of 11h. 30m. silly, he only shrugged.
OTHERS IN RACE
Others in the Bendix race will be Frank Fuller and Miss Cochran in Seversky planes, Robert Perlick, Glendale, in a Beechcraft; Robert Hinschey and Charles LaJotte, Glendale, in a Sparton; Ross Hadley, Burbank, in a Beechcraft; George Armistead, Los Angeles, in a Q.E.D. Special; Bernarr Macfadden, New York publisher, and Ralph Francis, former TWA pilot, in a Northrop Gamma; Paul Mantz, Burbank, in a Lockheed Orion; Frank Cordova, New York, in a Bellanca; Lee Gehlbach, New York, in a Wedell-Williams, and Max Constant, Burbank, in a Beechcraft.

NX1384 was built especially for Jackie Cochran. The AP-7 racer was an improved version of Seversky’s P-35A fighter, which was the U.S. Army Air Corps’ first all-metal single-engine airplane with an enclosed cockpit and retractable landing gear.
Cochran’s AP-7 was powered by an air-cooled, supercharged, 1,829.39-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S1B3-G (R-1830-11) two-row 14-cylinder radial engine with a compression ratio of 6.7:1. It was rated at 850 horsepower at 2,450 r.p.m. at 5,000 feet (1,524 meters), and 1,000 horsepower at 2,600 r.p.m. for take off. The engine turned a three-bladed Hamilton-Standard controllable-pitch propeller through a 3:2 gear reduction. The R-1830-11 was 4 feet, 8.66 inches (1.439 meters) long with a diameter of 4 feet, 0.00 inches (1.219 meters), and weighed 1,320 pounds (599 kilograms).

Two days later, 1 September 1938, Jackie Cochran flew this same airplane to win the Bendix Trophy Race from Burbank to Cleveland, Ohio, a distance of 2,042 miles (3,286 kilometers). Her winning time was 8 hours, 10 minutes, 31.4 seconds, for an average speed of 249.774 miles per hour (401.895 kilometers per hour). After a 40 minute refueling stop, and being congratulated for her Bendix win, she flew on to Bendix, New Jersey, setting a West-to-East Transcontinental Speed Record with a total elapsed time of 10 hours, 7 minutes, 1 second.
The Seversky AP-7 and its military version, the P-35, would be developed over the next few years to become the Republic P-47 Thunderbolt.

Captain Richard Stephen Ritchie, United States Air Force
28 August 1972: Captain Richard Stephen Ritchie, United States Air Force, and Weapons System Officer Captain Charles Barbin DeBellevue, leading Buick flight with their McDonnell F-4D Phantom II, shot down a North Vietnamese MiG 21 interceptor. This was Ritchie’s fifth confirmed aerial combat victory, earning him the title of “ace.” [Chuck DeBellevue would later be credited with six kills.]
An official U.S. Air Force history reads:
. . . Ritchie flew the lead aircraft of a MiGCAP flight, with Capt. Charles B. DeBellevue as his WSO, during a Linebacker strike mission. “We acquired a radar lock-on on a MiG 21 that was head-on to us,” Ritchie said.
“We converted to the stern and fired two AIM-7 missiles during the conversion. These missiles were out of parameters and were fired in an attempt to get the MiG to start a turn. As we rolled out behind the MiG, we fired the two remaining AIM-7s. The third missile missed, but the fourth impacted the MiG. The MiG was seen to explode and start tumbling toward the earth. The kill was witnessed by Captain John Madden, aircraft commander in number 3.

“It was an entirely different situation,” Ritchie noted to newsmen. The MiG flew at “a much higher altitude than any of my other MiG kills and at a much greater range. I don’t think the MiG pilot ever really saw us. All he saw were those missiles coming at him and that’s what helped us finally get him.”
The new ace complimented the ground crews who kept the F-4s combat ready: “There’s no way could have done it without them,” he said. In fact, I got my first and fifth MiG in the same plane. Crew Chief Sergeant Reggie Taylor was the first one up the ladder when the plane landed and you just couldn’t believe how happy he was. I think he was more excited than I.”
DeBellevue, whose total victories rose to four with this day’s kill, commented on the teamwork: “The most important thing is for the crew to work well together,” he said. “They have to know each other. I know what Steve is thinking on a mission and can almost accomplish whatever he wants before he asks. I was telling him everything had to know when he wanted it, and did not waste time giving him useless data.”

28 August 1961: Operation SAGEBURNER: To commemorate the 50th anniversary of Naval Aviation, Lieutenants Huntington Hardisty and Earl De Esch, United States Navy, flew a McDonnell F4H-1F Phantom II to a Fédération Aéronautique Internationale (FAI) World Speed Record of 1,452.777 kilometers per hour (902.714 miles per hour) over a 3 kilometer (1.864 mile) course at White Sands Missile Range, New Mexico. They flew BELOW 125 feet (38.1 meters) above the ground.

An earlier speed record attempt, 18 May 1961, ended tragically when Commander Jack L. Felsman, and Ensign Raymond M. Hite, Jr., were killed and their F4H-1F Phantom II, Bu. No. 145316, destroyed when a pitch damper failed which resulted in Pilot Induced Oscillation. This became so severe that the Phantom’s airframe was subjected to 12 Gs, causing it to break apart in flight. Both engines were torn from the airframe.

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.

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 2006.
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.

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.
Walter Shirley died in 1993.
