A helicopter is a vehicle which can fly in the air.
It is different from the aeroplane. It has rotors on the top which rotate very fast. It has landing gears, cockpit for pilot and others to sit and also tail rotors.
A helicopter can remain still while in the air. It can be landed anywhere and does not require a runway to land or fly.
A helicopter is very useful. It is used in military, as ambulance, as passenger bus, for construction, and also for emergency purposes.
Helicopter is an important part of today’s society. However, a little bit of problem or mistake can lead to crash and death.
