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:
“Sure smokers have made personal choices. And they pay for those choices every day, whether sitting through an airline flight dying for a smoke, or dying for a smoke in the oncology wing of a hospital. The tobacco companies have not paid nearly enough for the killing.”
—Anna Quindlen (b. 1952)
