caption_attribution_description: Jacques Trempe collected aircraft photos that were sent by government agencies, aircraft manufacturers and the like from childhood. The photo in question was taken by a member of the British government and intended for use as a promotional piece in the 1950s.
context_page_description: This is a list of experimental aircraft, or aircraft used or built to conduct experiments involving aerodynamics, structural materials, propulsion systems, configuration and equipment. Prototypes, pre-production and homebuilt aircraft described as experimental but which were not used in this manner outside their own development are excluded.
