When the upwardly force of the air opposition equals the jumpers weight then he experiences zero accele ration or a freefall. The heavier the jumper the high the magnitude of the freefall, this is because air resistance is proportional to the falling bodys speeding squared. In training astronauts for a real weightlessness environment NASA incorporates weightlessness training programs.

virtuoso such program is nicknamed the vomit comet. This is an airplane, the KC-135, which allows the astronauts to experience weightlessness for 30 second intervals. The plane flies in a series of parabolic patterns. This was first done in July of 1978 by Guion S. Bluford. other way they experience weightlessness is in a simulator.
