More important, say Convair's experts, is the possibility that raindrops can puncture a jet's fuselage or cockpit blister, causing the pressurized cabin to explode at high altitudes. At 1,520 m.p.h. (Mach 2), a raindrop smashes into a plane with a force of 70,000 Ibs. per sq. in. At higher speeds, raindrops may be as deadly as enemy bullets...
...week, the Air Force was prepared to invest heavily to make hallucination come true. Air Force men have inspected a Canadian mockup saucer, approved a more advanced design, and hope within three years to have a prototype that can take off straight up, hover in midair, and fly at mach 2.5 [nearly 2,000 m.p.h. at sea level]. Its designer: John C. M. Frost, 35, a tall, shy Briton with a passion for flowers and flying saucers...
...flying had given the Air Force a stamp of its own - a skill to rival the technical proficiency of the Navy. For another, the new Air Force was a rich mixture of two generations of flying men: combat-tested elders teamed with youngsters born under the sign of Mach...
Instead of shock, he gets heat. Air hitting a body moving at Mach 10 raises its surface temperature by 7,500°F. This is not so bad as it looks at first glance; there is so little air that not much heat is transferred to the speeding body. The pilot or his capsule, nevertheless, needs protection against heat damage...
When the pilot has slowed to about Mach 1 below 100,000 ft., he needs protection not from heat but from cold. He also needs oxygen, and when his low-altitude parachute has opened and he has settled safely to earth, he may need a compass, map, food and other survival supplies. He will not be easy to find: his initial speed will have carried him 250 miles horizontally from the point where he left his airplane...
