Alan Douglas Carden (July 1874 – April 1964) was a British pioneer aviator who rose to the rank of Colonel in the Royal Engineers.
[citation needed] On 2 January 1913 he married Elizabeth Nie Constance Mary, widow of Captain J. D. Dauncey of the Dorsetshire Regiment.
Carden joined Dunne's Blair Atholl Aeroplane Syndicate and bought the first D.8 biplane so that he could learn to fly.
[4] Carden attached a ring prosthesis over the stump of his injured arm and found that he could operate the lever satisfactorily.
Two years later the battalion was dissolved and reformed as the Royal Flying Corps, and Carden rose to Squadron-Leader with the (initially temporary) rank of Major.
[2] On the outbreak of war he went to France and established the RFC's central aircraft park, including the Engine Repair Shop (ERS).
