Wikipedia:
An
aircraft is a
vehicle which is able to
fly by being supported by the
air, or in general, the
atmosphere of a planet. An aircraft counters the force of gravity by using either
static lift (as with
balloons,
blimps and
dirigibles) or by using the
dynamic lift of an
airfoil (as with vehicles that plane the air with
wings in a straight manner, such as
airplanes and
gliders, or vehicles that generate lift with wings in a
rotary manner, such as
helicopters or
gyrocopters).
[1] Although
rockets and most
missiles also travel through the atmosphere, most are not considered aircraft because they use rocket thrust and ballistics instead of aerodynamics for the primary means of lift. A
cruise missile on the other hand relies on a lifting wing throughout the majority of its flight regime, and may be considered to be an aircraft.
The
human activity which surrounds aircraft is called
aviation. Manned aircraft are flown by an onboard
pilot.
Unmanned aerial vehicles may be
remotely controlled or self-controlled by onboard computers.
Target drones are an example of UAVs.
