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.

The dawn of air travel. On 19 August 1919, Aircraft Transport & Travel (AT&T) inaugurated the world's first scheduled international air service. On that day, sister ship G-EAJC arrived at Le Bourget from Hounslow Heath aerodrome, near Heathrow, carrying one passenger, a consignment of leather, several grouse and some jars of Devonshire cream. G-EAJD is ex F2704 and the overpainted serial is still visible on the rudder. Photo from: Bibliothèque nationale de France - Gallica

The British DH.4 was one of the best light bombers of WWI. A huge number were built in the USA in 1918. This airframe was rebuilt for the US Post Office by Boeing in 1923. It was later owned by movie stunt pilot Paul Mantz.

The DH-4 was a 1917 RAF day bomber. Examples sank German submarines and shot down Zeppelins at up to 16000 ft. 4,587 were US-built, mainly with Liberty engines, for service with the Army Air Service in Europe. Postwar the DH-4 remained in US military service until 1929. No.166 was one of over 100 upgraded DH-4Bs used postwar on transcontinental airmail routes by the USPO. 400 lbs of mail was carried in a compartment replacing the forward cockpit. From Douglas A/c.
