...what it hopes will be the world's first supersonic commercial transport. Federal Aviation Administrator Najeeb Halaby, asked by the Kennedy Administration to investigate the feasibility of such a plane, spelled out the desired quality of what he called "the monster." The new plane should cruise at Mach 3 (about 2,000 m.p.h.) at an altitude of 65,000 to 75,000 feet, fly from Los Angeles to New York in 74 minutes, and zip across the North Atlantic in less than two hours...
...credit for new doctrine, McNamara will catch most of the blame for drastic cuts he has ordered in existing programs. Among them: curtailment of the liquid-fueled, obsolescent Titan ICBM and "low reliability" Snark missiles and a virtual end to the development of the Air Force's cherished Mach 3 bomber of the future, North American's B-70, as well as the perennially experimental nuclear airplane. These slashes are sure to bring cries of anguish from pressure groups (both in and out of the Pentagon) and contractors, but none will be so loud or perhaps so damaging...
Kennedy called for a sizable cut ($138 million) in Eisenhower's $354 million request for the 6-70 program, the Air Force's Mach 3 bomber of the future, and hacked $50 million more from nuclear airplane development. Unexpected was the severe hatcheting of military installations: the Pentagon hopes to close down no fewer than 73 posts both in the U.S. and overseas, plans to reassign the 24,000 civilians who work at them...
Skid Landing. Coming down, White put his plane into a cautious glide that permitted it to slow to Mach 3. Then he opened his speed brakes: four doorlike vanes near the tail that open into the air stream to add drag. They brought him down to Mach 2, which is strolling speed for the X-15. He decelerated gradually to subsonic speed, was soon in position for his landing approach at Rogers Dry Lake. Three miles from the touchdown point, he jettisoned the fin under the tail to clear the landing skids, and skidded to a clean landing...
...itself could have talked, it might have complained about the heat of the flight. A thermocouple inside the wing recorded 675° F. Yet the structure did not fail, and the engineers are confident that it can take its design temperature of 1,200° F., reach Mach 6 and climb to 50 or perhaps 100 miles...
