A reduced gravity aircraft is a type of fixed-wing aircraft that provides brief near-weightless environments in which to train astronauts, conduct research and film motion pictures.
Versions of such airplanes, officially nicknamed Weightless Wonders, have been operated by the NASA Reduced Gravity Research Program. The unofficial nickname "Vomit Comet" became popular among those who experienced their operation.

Famous quotes containing the words reduced and/or gravity:
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!—But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (1803–1882)
“Here I sit down to form characters. One I intend to be all goodness; All goodness he is. Another I intend to be all gravity; All gravity he is. Another Lady Gish; All Lady Gish she is. I am all the while absorbed in the character. It is not fair to say—I, identically I, am anywhere, while I keep within the character.”
—Samuel Richardson (1689–1761)
