...National Aeronautics and Space Administration approved models of one-ton mushroom-shaped satellite capsules designed to fly men into space in the early 1960s. The model satellites survived preliminary tests of rocket shots into the atmosphere, drops from high-altitude aircraft, wind-tunnel speeds of 10,000 m.p.h., and justified what NASA termed "significant progress" toward "a safe and reliable, manned satellite capsule...
...Cavern, which lies at its southern end, eight experienced "potholers," under the auspices of Britain's Speleological Association, last week began the exploration of a newly discovered underground passage. They first worked their way in by a series of up and down scrambles, then wriggled through a narrow tunnel with a mud floor and a roof that was sometimes no more than 10 in. above their heads. It took them two hours to progress 600 ft. The tunnel suddenly broadened into a fairly large chamber 1,000 ft. beneath the surface. Leading off from the chamber was a shaft...
...R.A.F. mountain rescue unit arrived, followed by crack rescue groups from the National Coal Board and the submarine base at Gosport. Hospitals sent cylinders of oxygen. The rescue workers struggled through the mud and darkness, slithered into waist-high pools. Fifty volunteers were spaced out at intervals in the tunnel to make a hand chain for passing on ropes, food, lamps, oxygen cylinders...
...tunnel's mouth, Cotton Executive Eric Moss, who had been on the site since the news of the accident reached him, said: "I don't want anybody else to risk their lives by trying to get my son's body out. Let's leave him where he is." But rescuers, who thought such a decision "goes right against the grain of every potholer," got permission to drive a new 20-ft. tunnel to get Moss's body out, because "it will teach us a lot in avoidance of future accidents...
...outfielder in his college days at Michigan State, Dr. Briggs left nothing to chance in his experiments. He measured speed and spin in the National Bureau of Standards wind tunnel. For live experiments, Dr. Briggs measured the curve-throwing ability of the Washington Senators' staff in Griffith Stadium, found the best of them could break off a curve at 1,600 r.p.m. Presumably, better pitchers on other clubs could approach 1,800 r.p.m., achieve the maximum curve. As for speed, 100 ft. per sec. is well within the range of a big-league pitcher. Fastest pitch ever recorded...
