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.

“I’ve tried to reduce profanity but I reduced so much profanity when writing the book that I’m afraid not much could come out. Perhaps we will have to consider it simply as a profane book and hope that the next book will be less profane or perhaps more sacred.”

“Grown beyond nature now, soft food for worms,
They lift frail heads in gravity and good faith.”
