The helicopter was invented in the 1920s but not commercially made or used.

It was just a simple helicopter that was not meant to fly or be sold like today's helicopters.

Then on September 14th 1939 the world's first practical helicopter, took flight at Stratford, Connecticut. Designed by Igor Sikorsky and built by the Vought-Sikorsky Aircraft Division of the United Aircraft Corporation, the helicopter was the first to incorporate a single main rotor and tail rotor design.

A helicopter is able to easily hover in one spot for as long as it has fuel to operate.

An example would be if the helicopter needs to rescue someone and they need to hover over that spot to lower the rescue worker and then raise the rescue worker and person back up to the helicopter and then take off.

Helicopters are able to hover in one spot for an extended period of time and move backwards, forwards and sideways etc easily.

That is unlike an airplane that is not as versatile.

Helicopters also usually have a autopilot hover option that allows the helicopter to hover in one spot without the pilot needing to control it much.
