...total shutdown to Broca's area had lasted six minutes or more, Eisenhower would have lost the power of coherent speech; at normal blood heat, brain cells cannot survive longer than that without oxygen-bearing blood. Evidently the shutdown was incomplete or for a shorter period because, although the cells in Broca's area had been damaged, the damage was not severe: overnight the doctors observed improvement in the President's speech. Adequate blood flow to the oxygen-starved cells had been restored...
...aluminized fabric to protect the inner layers and to reflect solar or A-bomb heat. Inside is a coverall of special, airproofed nylon material carefully fitted to the individual wearer's body. In its normal, pressureless state, it is flexible and reasonably comfortable (see cut). Cold air or oxygen can be pumped through it to cool the pilot if his cabin gets...
Unless something goes wrong, the suit stays relaxed, but if the cabin loses its pressure at, say, 150,000 ft., an automatic valve shoots oxygen into the suit from the airplane's supply. The inner suit blows up like a man-shaped balloon. Complicated pressure-and temperature-regulating gadgets go into action, surrounding the pilot with an environment in which he can stay alive in spite of the near vacuum that has developed in the damaged cabin. He has at least a chance to fly the airplane down to livable...
Aramburu clapped on his bubble helmet and oxygen mask, and the plane climbed quickly to 26,000 feet. Somewhere around 700 m.p.h. the jet banged through the sound barrier, soon hit 800 m.p.h. Twenty-five minutes after takeoff, the President was back on the ground. How did he like it? "Fantastic," said Aramburu. "There's something about it you cannot explain." According to Air Force officials, Aramburu was the first chief of state ever to break the sound barrier...
...keeping down the rocket's size and frontal area. Ease of ignition is almost a must. The best combinations are "hypergolic," igniting spontaneously as soon as mixed. Bad qualities to be avoided are toxicity, corrosiveness, heat instability (exploding when hot) and a tendency to evaporate like liquid oxygen. No fuel is perfect. Beryllium compounds might be good if beryllium were not so scarce and so poisonous...
