Publisher's Synopsis
Helicopters are a type of flying transportation device. They can fly, hover, and move side-to-side and forward, and they can land in small areas. It is important to understand how a helicopter works so that you can get the best use out of them. Helicopters are generally slower than airplanes. They also have limitations, such as the fact that they cannot fly in the dark. However, they are perfect for tourism, search and rescue, aerial photography, and military activity.
