Drone

A drone is an unmanned aerial vehicle, which is usually supervised by people on the ground. Sometimes they are programmed to a particular target.

The first drones were unmanned balloons loaded with explosives that were launched from the Austrian ship Vulcano on August 22, 1849.

Drones come in different sizes. Wingspans range from a few centimeters to about 60 meters (200 ft), the size of regular, manned aircraft.

The first passenger drone was approved for test flights in the U.S. in June 2016. The Chinese-made Ehang 184 AAV (autonomous aerial vehicle) can carry one passenger. It has no override function, so, in an emergency, the passenger cannot take control.

Drones are banned in all US National Parks.

In 2000 the US had only 50 military drones; today it has over 7,500.
