The Alliance P.2 Seabird was a British single-engined long-range biplane designed by J.A. Peters to enter the Daily Mail £10,000 Atlantic Flight Prize. In the end it did not compete but became the first aircraft to fly from London (Acton) to Madrid non-stop on 31 July 1919.[1]
The Alliance Aeroplane Company which had constructed aircraft under licence during the First World War decided to build aircraft for the civil market. The Seabird was a long-range two-seat biplane powered by a 450 hp (336 kW) Napier Lion piston engine.[1] With an endurance of 21 hours it had an enclosed cabin for the crew of two and two aircraft were built.[1]
On 17 April 1919 Peters the designer paid the £100 entrance fee to the Royal Aero Club as entry fee for the Alliance biplane into the competition for the Daily Mail £10,000 Atlantic Flight Prize.[2] Flown by Peters with Captain W.R. Curtis of the Royal Air Force the first Seabird (registration G-EAGL) carried out a trial flight on 31 July 1919 when it made the first direct non-stop flight between London and Madrid, 900 miles in just under eight hours.[3] The aircraft did not in the end compete in the Atlantic competition.
The second aircraft G-EAOX was entered into an Australian Government prize of £10,000 for a flight from Great Britain to Australia.[1][4] Flown by two Australian airmen, Lieutenant Roger Douglas (pilot) and Lieutenant J.S.L. Ross (Navigator), G-EAOX left Hounslow Heath Aerodrome on 13 November 1919 but a few minutes into the flight the Seabird crashed near Surbiton killing both airmen.[4]
The company never recovered from the accident and was closed down in 1920.
