Flight
Transport category airplanes, such as commercial airliners, use compressed air starters to start the main engines. The air is supplied by the load compressor of the aircraft's auxiliary power unit, or by ground equipment.
Water rockets use compressed air to power their water jet and generate thrust, they are used as toys.
Air Hogs, a toy brand, also uses compressed air to power piston engines in toy airplanes (and some other toy vehicles).

Famous quotes containing the word flight:
“When the flight is not high the fall is not heavy.”
—Chinese proverb.
“It is marvelous indeed to watch on television the rings of Saturn close; and to speculate on what we may yet find at galaxy’s edge. But in the process, we have lost the human element; not to mention the high hope of those quaint days when flight would create “one world.” Instead of one world, we have “star wars,” and a future in which dumb dented human toys will drift mindlessly about the cosmos long after our small planet’s dead.”
—Gore Vidal (b. 1925)
“No Raven’s wing can stretch the flight so far
As the torn bandrols of Napoleon’s war.
Choose then your climate, fix your best abode,
He’ll make you deserts and he’ll bring you blood.
How could you fear a dearth? have not mankind,
Tho slain by millions, millions left behind?
Has not conscription still the power to weild
Her annual faulchion o’er the human field?
A faithful harvester!”
—Joel Barlow (1754–1812)
