World War II In 1944, Topp was selected for pilot training and sent to Canada under the
British Commonwealth Air Training Plan. In 1950, Topp attended the
Empire Test Pilots' School at Farnborough and remained as a test pilot at the
Royal Aircraft Establishment (RAE). He conducted high-risk trials, including airborne structural testing of the
de Havilland Comet following catastrophic crashes in the Mediterranean, earning a second Bar to his AFC in 1955. Facing low morale, he introduced aerobatics to boost the squadron's spirit, forming the Black Arrows in 1956. Under his leadership, the Black Arrows performed a world record-breaking loop of 22 Hawker Hunters at the 1958 Farnborough Air Show, followed by the first-ever 16-aircraft barrel roll. Topp also set a speed record on 8 August 1956, flying a Hawker Hunter from Edinburgh to London at an average speed of 717.504 mph, covering 331.6 miles in 27 minutes and 52.8 seconds. ==Personal life==
