vomit comet
Zero-gravity training aircraft
A vomit comet is an aircraft that flies in parabolic arcs to create brief periods of weightlessness, used for astronaut training and zero-gravity research.
The nickname comes from the nausea these repeated dives induce in passengers: I got to experience weightlessness on the vomit comet.
NASA's official term is "reduced gravity aircraft."
