What Can A Helicopter Do?
A helicopter's rotors allow it to do things an airplane cannot. Unlike an airplane, a helicopter does not have to move quickly through the air to have lift. That fact means it can move straight up or down. Most airplanes cannot do this. A helicopter can take off or land without a runway. It can turn in the air in ways airplanes cannot. Unlike an airplane, a helicopter can fly backwards or sideways. It also can hover in one spot in the air without moving. This makes helicopters ideal for things an airplane cannot do. For example, a helicopter can pick someone with a medical problem up where there is no runway. It can then land in a small area on top of a hospital.
