Beecraft Wee Bee (1948)
Самолётик целиком металлический! Но вес пилота ограничен.
During the late 1940s, American aviation company Beecraft designed the then smallest airplane in the world. It was made entirely of metal, just like the modern planes of the day, but had a wingspan of just 5.49 meters (18ft).
Due to the tiny dimensions of this aircraft, the pilot, quite extraordinarily, had to lie down in a prone position on top of the fuselage! Talk about a wild ride. The airplane had a 30-hp piston engine and weighed just 95kg. Despite this, it could still carry 90kg in the form of its pilot. (flitetest.com)
