| Text | #3551450 (Length: 675 characters) Chinese children played with them c. 400 BC; da Vinci designed one in the early 1480s; the Frenchman d'Amecourt demonstrated a steam-powered aluminum one in 1861 (although it never got off the ground); in 1907 two Frenchmen, the Breguet brothers, finally built an engine-powered helicopter which lifted its pilot two feet off the ground. And in 1933 the German Focke-Wulf company designed and built the world's first twin-rotor helicopter, intending it for military use, even as Igor Sikorsky was doing the same in the United States. Used rarely during WW2, the helicopter was primarily employed as transport in the Korean War, and finally as gunships during the Vietnam War. |
