Aircraft

An aircraft is a type of craft designed for atmospheric flight, and were in common usage on the planet Earth during the 20th and 21st centuries. Airplanes were different from spacecraft as they were usually designed to fly no higher than the upper reaches of Earth's atmosphere.

Examples of these craft include balloons, fixed-wing airplanes or jets, and rotary-wing helicopters.
