helicopters

A helicopter is a type of aircraft that can take off and land vertically, hover in place, and fly in any direction. It achieves this through rotating blades called rotors, which generate lift and thrust by spinning rapidly. Unlike airplanes, which need runways, helicopters can operate in confined spaces and are useful for rescue, transport, and surveying. Their design allows for precise maneuvering and access to hard-to-reach areas, making them versatile tools in various industries.
