Powered Flight
A powered aircraft is an aircraft that uses onboard propulsion with mechanical power generated by an aircraft engine of some kind.
Aircraft propulsion nearly always uses either a type of propeller, or a form of jet propulsion. Other potential propulsion techniques such as ornithopters are very rarely used.

Famous quotes containing the word flight:
“Fear of error which everything recalls to me at every moment of the flight of my ideas, this mania for control, makes men prefer reason’s imagination to the imagination of the senses. And yet it is always the imagination alone which is at work.”
—Louis Aragon (1897–1982)
