De Havilland D.H.10a Amiens IIIA F8423, Aeroplane Experimental Establishment, Martlesham Heath: Written off (destroyed) 10/3/21 when went out of control and spun and crashed on test flight at Gull Farm, Hasketon, Suffolk. Pilot - Flying Officer Harold William Gardner (aged 27) - was killed

A little more detail is given by the Casualty Card at the RAF Museum, which confirms the unit as the Aero Experimental Establishment, and the date and time as 10.3.21 at 11hrs. There is a link to a Secret file S.15072, but if we follow a “P.T.O.” in green ink, on the reverse we read: "Purpose of Flight. Practice flight on type of machine new to Pilot."

Finding of Court of Inquiry: "The Aeroplane stalled after coming out of a left handed spin: there not being sufficient height for the Pilot to get control again. There is no evidence to show why the Aeroplane got into a spin."
