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:
“Its shrill scream seems yet to linger in its throat, and the roar of the sea in its wings. There is the tyranny of Jove in its claws, and his wrath in the erectile feathers of the head and neck. It reminds me of the Argonautic expedition, and would inspire the dullest to take flight over Parnassus.”
—Henry David Thoreau (1817–1862)
“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)
“AIDS was ... an illness in stages, a very long flight of steps that led assuredly to death, but whose every step represented a unique apprenticeship. It was a disease that gave death time to live and its victims time to die, time to discover time, and in the end to discover life.”
—Hervé Guibert (1955–1991)
