What does all of this add up to? Harvard wants to play the kind of solid, fast breaking, depth-utilizing type of basketball which last year was the exception and this year has proved to be the rule...
Much of the public quizzing focused on the Challenger's two solid-fuel rocket boosters, each 149 ft. tall and 12.2 ft. in diameter. Photographs released by NASA left no doubt that an abnormal plume of flame had appeared on the right-hand booster just before a huge fireball engulfed the entire space vehicle. Although NASA's acting administrator, William Graham, said the flame's location had not been pinpointed, it appeared to be about 36 ft. above the bottom of the rocket's nozzle, near an attachment ring where the lower part of the booster was connected...
...only 13 seconds to discover the problem and react. But NASA officials testified that escape would have been impossible in any case. Arnold Aldrich, shuttle manager at the Johnson Space Center, told the commissioners that Challenger could not have separated from the boosters and the tank until the solid-fuel rockets had completed their uncontrolled firing, about two minutes after lift-off. Any earlier separation, he said, would have thrown the shuttle into the wake of the powerful rocket motors, a situation that "is thought to be unsurvivable...
...only 38 degrees at the 11:38 a.m. lift-off. Buffeted by overnight winds of up to 35 m.p.h., the shuttle had gone through what meteorologists call a "cold soak," conditions more severe than those at any of the previous 24 shuttle launches. NASA manuals say that the solid fuel in a booster should be ignited only when the rubber-like mixture is between 40 degrees and 90 degrees . Morton Thiokol, the rocket manufacturer, also specifies that the fuel's temperature should never be allowed to fall below freezing. The insulated boosters contain no internal heat sensors, but NASA technicians...
