A helicopter is a type of aircraft that can take off and land vertically, making it very versatile. Unlike airplanes, which need long runways, helicopters can fly in and out of tight spaces. They use rotating blades, called rotors, to lift off the ground and move in different directions. This ability allows them to reach places that other vehicles cannot, such as remote areas or crowded cities. Helicopters are used for many purposes, including medical emergencies, search and rescue, and news reporting. They can quickly transport people and supplies, making them essential in situations where time is critical. With their unique design, helicopters play a vital role in our modern world.
