The first fully controllable helicopter was invented in 1939 by Igor Sikorsky.
Helicopters have more maneuverability than airplanes. That means they are easier to move, and change directions. They are able to hover in place, reverse, as well as land and take off vertically.
Today helicopters are used by the air force,as well as tv networks, police, farmers and regular people with passenger helicopters.
