    The helicopter is a type of an aircraft and undoubtedly is one of the most important and versatile vehicle in the world. It can move in all the directions including backwards and can land and take off vertically. The thing that enables it to fly is rotor blades that work in the same way as it does for the airplane. When these blades spin, air moves faster over the top of the blades and pushes the air downwards that creates lift for the flight.
