A helicopter is an aircraft that has

fast-spinning wings, called “rotor

blades,” on top and in back, that

lift it into the air. Helicopters

can fly up, down, forward, or

even backward. They also have a

special ability called “hovering,”

staying in the same spot in midair.

Helicopters can take off and

land in very small spaces and at

a moment’s notice. This makes

them perfect for all sorts of

jobs. Police officers, firefighters,

doctors, news reporters,

and farmers all use them.
