Also, the long bones lay perpendicular to the force vector, so ther are less likely to fail. Why do we feel weightless in elevators? - Wise-Answer . It seems more practical to jump up at 30 mph (partial impact cancellation) which can effectively cut down the 'g' forces by distributing the braking distance, sort of like the last second "braking" rockets of cosmonaut space craft that fire just before a parachute landing. If the elevator has been falling for more time, then the injuries would be much more grievous. This is called free fall, and it is this acceleration which results in the sense of weightlessness.
