When my grandpa was navigating B24's in WWII, he saw a B24's wing flying by itself. The Japanese had set the plane on fire from nose to tail, and the body separated from the wings. The B24 has the wings on top of the fuselage, so the wings could stay together. The body, of course, fell into the clouds below, but the wings stayed aloft. And naturally, because they didn't have to carry a fuselage around, they accelerated, and lazily curved out of sight of grandpa, who thought he might have been the only person to ever see something like that (and survive to tell the tale...)
