The DH.4A was developed for use on the military cross-Channel service operated by No. 2 (Communicaton) Sqn between Kenley and Buc during the negotiations for the Versailles treaty. Five DH.4s, including F5764, were modified to seat a minister and his secretary face to face in a glazed cabin so that work might continue during the flight. To compensate for the weight of the third occupant, the upper wing was moved aft one foot, meaning the DH.4A had no stagger. Four new DH.4s were also completed as DH.4As for Airco's subsidiary Aircraft Transport & Travel in July 1919. F5764 became G-EAWH with Handley Page Transport.
