One of the original 16 pilots of Imperial Airways in 1924

September 1925: "A new air record was created Friday, when Mr. A. L. Robinson, an Imperial Airways pilot, flew a Napier D.H. Express carrying six passengers from Londonto  Amsterdam, a distance by air of 275 miles, in 110 minutes. His average speed was 150 miles per hour."

His was a rather chequered career; apparently there was a rumour that he insisted on being paid in cash because the taxman was after him. This is from the Western Daily Press, 2 May 1934:

"Arthur Leonard Robinson (38), a wartime flying officer, stated to have been formerly employed as a pilot by Imperial Airways, was sentenced at London Session, yesterday, to six months' hard labour for obtaining credit by fraud from a London restaurant"

During WW2 he flew with the ATA, and later as a test pilot for Rolls Royce at Hucknall.

d. in 1950:

"ROBINSON Arthur Leonard of 21 Marshall-drive Bramcote Nottingham died 30 September 1950 Administration Liverpool 17 November to Irene Mabel Robinson widow. Effects £2,478 5s 8d." (which sounds quite a lot to me; I wonder how he got it?)
