We may not have to do every experiment from here on out in a parabolic flight," said Strangman.
After climbing to around 30,000ft, the aircraft uses a technique called parabolic flight to achieve weightlessness - the same method used to train astronauts and to film Apollo 13.
It would also be interest to anyone who wonders the concepts like momentum possessed, whole body angular momentum, opposite parallel forces, superman position, parabolic flight path, joint/normal reaction force, etc.
