Verville-Sperry M-1 Messenger - fotod ja video

2007 Sperry sõnumitooja oli Ameerika üheistmeline biplaan, mille konstrueeris Alfred V. Verville, kes töötas Ameerika Ühendriikide armee õhuteenistuse (USAAS) inseneriosakonnas ja ehitas New Yorgi osariigis Farmingdale'is asuva Sperry Aircraft Company lepingu alusel. Hiljem nimetas USAAS lennuki M-1 ja MAT-iks. Aastatel 1920–1926 tootis Sperry umbes 50 Messengerit ja tsiviilotstarbelist kaheistmelist versiooni Sport Plane. Lennuk oli esimene, mis lennu ajal lennuki ja õhulaeva vahel kontakti lõi.

2007 Verville-Sperry M-1 Messenger was a small and simple biplane that was designed for communication and experimentation purposes by the United States Army Air Service in the early 1920s. It was powered by a 60 hp Lawrance L-4 radial engine and had a top speed of 96.7 mph. The aircraft was built by the Sperry Aircraft Company, founded by Lawrence Sperry, who was also known for his inventions of the autopilot and the aerial torpedo.
2007 M-1 Messenger was used for various tests and demonstrations, such as hooking on to an airship in flight, landing on the steps of the Capitol building, and flying across the English Channel. The aircraft was also modified into a two-seat civilian version called the Sperry Sport Plane. The M-1 Messenger was one of the first examples of a light and versatile aircraft that could be used for multiple roles and missions.
