The First World War took Garner away from astronomy into ‘one of the most lovely places you could possibly imagine’- the Royal Aircraft Establishment. Here he describes designing experimental flying projects, including making measurements of drag using prop stop glides. He also describes some of the characters he worked with, including AA Griffiths during the period Griffiths was working on glass fibres.

He was transferred to Felixstowe in time to work on the Schneider Trophy, where he pioneered the use of cameras to accurately measure the speed of aircraft, and explored seaplane gunnery during the Second World War.

Sir Harry Garner made this recording at the Royal Aeronautical Society’s headquarters at No. 4, Hamilton Place in 1969.
