Brian Trubshaw was born in Liverpool in 1924  although he grew up in Llanelli where his parents lived at the time. He was educated at Winchester College. He signed up for the RAF in 1942 at the age of eighteen and went to the United States where he trained as a pilot flying Stearman biplanes. He joined Bomber Command in 1944, flying Stirlings and Lancasters, transferring a year later to Transport Command.
Trubshaw then went to Malaya when he was given permission to leave the RAF (Flight Lieutenant Trubshaw retired from the RAF at his own request on 21 May 1950) to take up a role as test pilot for Vickers Armstrongs, where he remained for 30 years; he succeeded G R 'Jock' Bryce as chief test pilot by 1964, and was director of test flighting from 1966. Trubshaw worked on the development of the Valiant V-bomber, the Vanguard, the VC10, and the BAC One-Eleven, and test flew all of these.
He shot to public attention when he first flew Concorde on 9 April 1969 on a flight from Filton to its test base at RAF Fairford. He emerged from Concorde 002's futuristic cockpit with the words: "It was wizard - a cool, calm and collected operation." Weeks earlier he had piloted an early test flight of the identical French prototype Concorde 001, commanded by André Turcat. Trubshaw and Turcat were both awarded the Ivan C. Kincheloe Award in 1971, for their work on Concorde.
He was appointed a Member of the Royal Victorian Order in 1948. He was awarded the OBE in 1964 and the CBE in 1970 and was awarded the French Aeronautical Medal in 1976. He ended his career as divisional director and general manager of the Filton works of British Aerospace from 1980-1986. From 1986-1993 he was a member of the board of the Civil Aviation Authority, and worked as an aviation consultant. He authored books on aviation, notably Concorde: The Inside Story.
