Question

The so-called zero-g airplane (sometimes called "vomit comet") flies in parabolic arcs to provide sensation of weightlessness to its passengers for brief periods of time (about 20 seconds). Along some of these parabolic arcs, as the airplane pulls up, the passengers feel not weightlessness but a sensation of "hypergravity," where they feel heavier than usual (often so heavy that it is difficult for the passengers to stand or sit upright). What happens to the passengers during these periods of hypergravity?
