Operational history

The Airspeed Viceroy started the race from RAF Mildenhall, England, but after several reliability problems including with the mainwheel brakes, it was withdrawn from the race at Athens. The pilots concluded that it would be unsafe to proceed and they would probably be unable to finish the race. An acrimonious set of legal actions followed, with the pilots complaining that the aircraft, beset by multiple problems, had been "not really ready". Airspeed contested the action, and eventually the aircraft was returned to them without refund. The aircraft returned to Portsmouth and was then stored until July 1936 when it was sold the following month by the French concern, SFTA and departed to France en route to the Spanish Civil War.

Documentation regarding the Viceroy's service with the Spanish Republican Air Force is sketchy. The intention was to convert the aircraft into a bomber and photographs suggest that it did receive new markings and was stationed at an airbase, but further information is not available as to its actual service.[1]
