An aircraft is a machine that is able to fly by gaining support from the air . It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil ,  or in a few cases the downward thrust from jet engines . Common examples of aircraft include airplanes , helicopters , airships (including blimps ), gliders , and hot air balloons . 
The human activity that surrounds aircraft is called aviation . The science of aviation, including designing and building aircraft, is called aeronautics . Crewed aircraft are flown by an onboard pilot , but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion , usage and others.
Flying model craft and stories of manned flight go back many centuries, however the first manned ascent – and safe descent – in modern times took place by larger hot-air balloons developed in the 18th century. Each of the two World Wars led to great technical advances. Consequently, the history of aircraft can be divided into five eras:
