...plane, but not so fast that the sudden acceleration will injure the human spine or break the hip bones. The prospects for this look fairly good. Wright Field workers have proved by experiments on themselves, says Baldwin, "that a man can take even the forces of 20 'Gs' [20 times the force of gravity] on his hip bones for a very short period without damage...

Even speeds now reachable, he mused, were pretty sticky for the pilots. "Bailing out is a bit of a problem. If a pilot bails out of a plane speeding 600 m.p.h., the air slows him down so suddenly that he gets a decelerating force of about 30 'Gs.' [Every part of his body weighs 30 times as much as normal.] This is a bit too much." To live, said Whittle, "the pilot will have to be tossed out in some sort of streamlined box," so he won't slow down too quickly...
Pouring on the Gs. In the circling cab, the human guinea pig will be strapped in a seat mounted on gimbals, so that it can be locked in any position. The air he breathes can be pumped away to simulate altitudes up to 60,000 feet. As the Gs begin to multiply, a television tube will stare him in the face, flashing his tortured grimaces to a screen in the control room. Elaborate instruments will study his fluttering heart; an electroencephalograph will record his troubled brain waves. An X-ray motion picture camera will photograph the slithering of his internal...
Human beings are not the only victims of G-trouble. As aircraft speeds increase, instruments and radio equipment too will be threatened by mounting Gs. In preparation for military invasion of the ionosphere, the Navy's new centrifuge will torture the robot crews of unmanned, guided missiles to see if their bloodless bodies can stand the punishment...
