Operational history

The first DH. 18 was delivered to Aircraft Transport and Travel for use on the Croyden-Paris service, but was wrecked in a forced landing shortly after takeoff from Croyden on 16 August 1920. Aircraft Transport and Travel Limited was a British airline formed during the First World War. Croydon Airport was an airport in South London which straddled the boundary between what are now the London boroughs of Croydon and Sutton. Paris (ˈpærɨs in English; in French) is the Capital of France and the country's largest city Events 1384 - The Hongwu Emperor of Ming China, Emperor Dong hears a case of a couple who tore paper money bills while fighting Year 1920 ( MCMXX) was a Leap year starting on Thursday (link will display 1920 of the Gregorian calendar [2] Two more aircraft were under construction by Airco for Aircraft Transport and Travel when the bankrupt Airco was purchased by BSA, who did not wish to continue aircraft development or production.

Aircraft Transport and Travel closed down in early 1921, due to competition from subsidised French airlines. This article is about the country For a topic outline on this subject see List of basic France topics. In March 1921, the British government granted temporary subsidies for airline services,[3] with the Air Council purchasing a number of modern commercial aircraft for leasing to approved firms. The Air Ministry was formerly a department of the British Government with the responsibility of managing the affairs of the Royal Air Force. [2] The three ex-A. T. &T. DH. 18s were purchased in this way and leased to Instone Air Lines. Instone Air Line was an early British airline from 1919 to 1924. A further DH. 18A was built to Air Council order, as were two modified DH. 18B, which had fuselages that were entirely plywood clad and had built in emergency exits. [2]

The DH. 18s were kept busy flying on continental air services for Instone, building up high flying hours. One aircraft, G-EAWO, was transferred to Daimler Hire Ltd for operation on the Croyden-Paris route until the De Havilland DH.34s which it had on order could be delivered. Daimler Air Hire was a private air hire company established June 7 1919 by Lieutenant Colonel Frank Searle CB, DSO, of WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout However, on 4 April 1922, two days after Daimler commenced operations with the aircraft, it collided with a Farman Goliath over Northern France,[2] 60 miles (100 km) north of Paris, killing seven people, the first mid-air collision between airliners. Events 1581 - Francis Drake completes a circumnavigation of the world and is knighted by Elizabeth I.

The DH. 18 was retired from commercial service in 1923, with one aircraft, G-EARO, having flown 90,000 miles (144,834 km) without accident. [2] Two aircraft were used for test purposes, with one the subject of an Air Ministry experiment on how long an aircraft could stay afloat after being ditched, being deliberately landed on water off Felixstowe on 2 May 1924, floating for 25 minutes. The Air Ministry was formerly a department of the British Government with the responsibility of managing the affairs of the Royal Air Force.
