John Vincent Cain

John Vincent Cain (1907 – 7 August 1940) was a British civilian aviator, AWOL soldier, convicted petty criminal, and confidence man who appeared as an unreliable narrator in newspaper coverage of 1930s European international relations. He may (or may not) have been involved in delivering planes and weapons to both sides of the Spanish Civil War. He was also apparently a passenger on the plane from which Max Wenner fell to his death in 1937. He himself committed suicide when about to be arrested in 1940.
