Helicopters 2D

The helicopter (from the Greek: ἕλιξ [helix], spira, spirale, and πτερόν [pterón], ala) is a type of aircraft used to transport people and things for civil and military use. It is generally equipped with one or more piston or turbine engines that operate a complex of blades that allow it to rise and fall vertically, remain stationary in flight, move laterally, backwards or forwards and perform flights similar to an airplane , but with greater flexibility and maneuverability.
