Handley Page Type L
|National origin||United Kingdom|
The Handley Page L/200 was the internal designation for a biplane aircraft by Handley Page, conceived to compete for the Daily Mail £10,000 prize for the first non-stop air crossing of the Atlantic. One prototype was designed and built in 1914 to the order of Princess Ludwig of Löwenstein-Wertheim.
The L/200 designation came from its 200 hp (150 kW) Salmson 2M.7 engine, but the engine was requisitioned by the Admiralty on arrival from France so although the aircraft was substantially built it was never finally assembled or flown. It was offered to the Admiralty as a coastal defence aircraft, with variants designated M/200 and MS/200 (seaplane) based on more readily available sub-100 hp (80 kW) engines, but these were not ordered as the Admiralty had already placed contracts for a seaplane for these duties.
The plans for the L/200 were lost by the time of the Commission on Awards to Inventors in February 1920 and no photographs remained either.
