Jet pack, rocket belt, rocket pack and similar names are used for various types of devices, usually worn on the back, that are propelled by jets of escaping gases (or in some cases liquid water) so as to allow a single user to fly.
The concept emerged from science fiction in the 1920s and became popular in the 1960s as the technology became a reality. The most common use of the jet pack has been in extra-vehicular activities for astronauts. Despite decades of advancement in the technology, the challenges of Earth's atmosphere, Earth's gravity, and the fact that the human body is not adapted to fly naturally remain an obstacle to its potential use in the military or as a means of personal transport.

Famous quotes containing the words jet and/or pack:
“I cannot beat off
Invincible modes of the sea, hearing:
Be a man my son by God.
He turned again
To the purring jet yellowing the murder story,
Deaf to the pathos circling in the air.”
—Allen Tate (1899–1979)
“... [Washington] is always an entertaining spectacle. Look at it now. The present President has the name of Roosevelt, marked facial resemblance to Wilson, and no perceptible aversion, to say the least, to many of the policies of Bryan. The New Deal, which at times seems more like a pack of cards thrown helter skelter, some face up, some face down, and then snatched in a free-for-all by the players, than it does like a regular deal, is going on before our interested, if puzzled eyes.”
—Alice Roosevelt Longworth (1884–1980)
