“On 14 December 1931, Douglas Bader flew to Woodley airfield near Reading. After lunch someone said, ‘I bet you won’t roll at nought feet.’ Bader did, and the graceful little Bulldog ended up in a shapeless ball of twisted metal. After hovering at death’s door Bader lost both legs. At Cranwell he remembered the Commandant had admonished him, ‘The RAF needs men, not schoolboys.’ Now he was neither, and the RAF would not need him anymore.”

Pilot Officer Douglas Robert Steuart Bader, Royal Air Force, caught the wingtip of his Bristol Bulldog Mk.IIA, K-1676, and crashed at Woodley Aerodrome, approximately four miles east of Reading, Berkshire, England. The airplane was damaged beyond repair.

Bader suffered major injuries requiring amputation of his right leg, followed by amputation of his left leg several days later. He was fitted with prosthetic legs with which he was soon able to walk without assistance. Pilot Officer Bader was medically retired and received a 100% disability pension.

In 1939, feeling that war with Germany was imminent, Bader applied to the Air Ministry for reinstatement. He was turned down, but was told that if there was a war his request might be reconsidered.

The Air Ministry did reconsider Douglas Bader’s request for reinstatement and after a medical evaluation and other tests, he was sent to refresher flight training where he was evaluated as “Exceptional,” a very rare qualification.

Group Captain Sir Douglas R. S. Bader, Royal Air Force, C.B.E., D.S.O. and Bar, D.F.C. and Bar, F.R.Ae.S., D.L., a legendary fighter pilot of the Royal Air Force during World War II, was born at St. John’s Wood, London, England. He joined the Royal Air Force in 1928 as a cadet at the Royal Air Force College Cranwell and was commissioned as a Pilot Officer in July 1930.

Credited with more than 20 aerial victories while flying Hawker Hurricane and Supermarine Spitfire fighters, Bader was himself shot down while flying his Spitfire Mk Va, serial W3185, marked “D B”. His prosthetic legs caught in the cockpit and made it difficult for him to escape, but he finally broke free and parachuted to safety.

Bader was captured and held as a prisoner of war. He was initially held at a hospital in occupied France and it was there that he met and became a life long friend of Adolf Galland, also a legendary fighter pilot—but for the other side! After arrangements were made for replacement legs, Bader escaped. He was recaptured and taken to the notorious Offizierslager IV-C at Colditz Castle where he was held for three years.

Douglas Bader is the subject of Reach For The Sky, a biography by Paul Brickhill, and a movie based on that book which starred Kenneth More.

Sir Douglas was invested Knight Bachelor, 12 June 1976, for his service to the disabled. He died suddenly of a heart attack, 5 September 1982.

The Bristol Type 105 Bulldog was a single-place, single-engine biplane fighter which served with the Royal Air Force from 1928 to 1938. It was constructed of a riveted framework of rolled steel strips. The forward fuselage was covered with light weight sheet metal, while the wings and aft fuselage were covered with doped fabric. The Bulldog Mk.IIA was 25 feet, 2 inches (7.671 meters) long with a wingspan of 33 feet, 10 inches (10.312 meters) and height of 8 feet, 9 inches (2.667 meters). It had and empty weight of 2,222 pounds (1,008 kilograms) and maximum takeoff weight of 3,660 pounds (1,660 kilograms).

The Bristol Bulldog Mk.IIA was powered by an air-cooled, supercharged, 1,752.79-cubic-inch-displacement (28.72 liter) Bristol Jupiter VIIF nine-cylinder radial engine which was rated at 440 horsepower up to 12,000 feet (3,658 meters). This was a left-hand tractor engine which drove a wooden two-bladed fixed-pitch propeller through a 2:1 gear reduction.

The airplane had a maximum speed of 174 miles per hour (280 kilometers per hour) at 10,000 feet (3,048 meters) and a service ceiling of 29,300 feet (8,931 meters).

The Bristol Bulldog Mk.IIA was armed with two synchronized Vickers .303-caliber machine guns with 600 rounds of ammunition per gun.

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.
