Verville-Sperry M-1 Messenger
The Sperry Messenger was an American single-seat biplane designed by Alfred V. Verville working for the Engineering Division of the United States Army Air Service (USAAS) and built under contract by Sperry Aircraft Company of Farmingdale, New York. The aircraft was later designated the M-1 and MAT by the USAAS. Sperry produced approximately 50 Messengers and the civilian two-seat version, the Sport Plane, between 1920 and 1926. The aircraft was the first to make contact between an airplane and an airship while in flight.
==Development==
In 1921 Alfred V. Verville led the Engineering Division of the USAAS's design of a simple single-seat biplane to be used as a messenger aircraft to replace motorcycles. The aircraft was built by the Sperry Aircraft Company as the Sperry Messenger. The Messenger was a conventional biplane with a fixed tailskid landing gear and a nose mounted 60 hp (45 kW) Lawrance L-4 radial engine. In 1924 the military aircraft were given USAAS designations M-1, M-1A and MAT. Lawrence Sperry gained attention when he landed his personal Messenger in front of the Capitol building and bounced up the front steps in Washington D.C. (See photo below.) He also successfully landed his little Messenger at the Lincoln Memorial. The prototype was used by Lawrence Sperry who disappeared in 1923, flying a Messenger across the English Channel from France to England.〔
