In 1963, Gilbert released The Wing Thing, an “all-weather flying vehicle” that stood a whopping 36-inches long by 48-inches wide. The mostly plastic toy was equipped with a .074 Thunderhead engine, so The Wing Thing flew under its own power, either free or tethered with a line attached. It was also capable of engine-less flight, doubling down as a rugged glider/kite that would spin and loop while gliding, thanks to an adjustable counter-weight on the fuselage.
