Winged tank

In war, airborne forces use parachutes to drop soldiers behind enemy lines to capture and hold important objectives until more heavily equipped friendly troops can arrive.

[1][2] In 1930, the Grokhovskiy Special Design Bureau experimented with dropping "air buses" full of troops: the bicycle-wheeled G-45 onto land, and the amphibious "hydro bus" into water.

When the hydro bus disintegrated on landing, the chief designer and his assistant were strapped into the G-45 for a test drop; they survived, but the project was cancelled.

[4] None of these were completely satisfactory, so in 1942 the Soviet Air Force ordered Oleg Antonov to design a glider for landing tanks.

Antonov was more ambitious, and instead added a detachable cradle to a lightened T-60 light tank, bearing large wood and fabric biplane wings and twin tail.

Although one semi-successful test flight was completed, due to the lack of sufficiently powerful aircraft to tow it at the required 160 km/h, the project was abandoned.
