One of 4,840 built in the USA under licence from de Havilland and is one of two original examples known to survive.

Welcoming the Douglas World Cruisers to Boston. DH-4M-2 aircraft were remanufactured with steel tube fuselage frames by Atlantic Fokker. The autogenous welding technique of Fokker - or rather, his master welder, Reinhold Platz - was still advanced in the early 1920s, and the DH-4 work put the American Fokker factory into business.

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

One of Dayton Wright's projects to extend the life of DH-4 production after Armistice. The aircraft was stretched by a foot to make a cabin for two behind the pilot. One can only speculate why it was called the Honeymoon. How many were built is unknown but there may have been only one. A Honeymoon won the Aviation Country Club Trophy Race at Detroit in 1922.

Dayton Wright used the DH-4 as the basis of several post World War I projects when military orders were cancelled. Nothing is known of the Sedan other than this photo was taken in early 1919. The location appears to be Deeds airfield which Dayton Wright used for test flying for aircraft built at its factory in nearby Moraine. Photo from: National Archives at College Park, Maryland

Became G-CYEC , an Air Board registration. The Air Board was an ostensibly civil organisation that fulfilled the role of an air force. The arrival of combat aircraft in the mid 1920s led to a dedicated Canadian air force and the eventual takeover of many Air Board aircraft. G-CYEC was struck off charge in 1928 before this happened.

G-AUBZ had a remarkably long career for an aircraft of its era. Registered in 1921, it was around long enough to became VH-UBZ. It was initially owned by legendary pilot Ray Parer, then went to Qantas and on to Matthews Aviation at Essendon. It remained in use into the late 1930s before being struck off the register in 1940, Photo from: National Library of Australia
