...leveled off, and a ground radar guided him toward the 18 km. (eleven mile) course that is specified by the F.A.I. (Fédération Aéronautique Internationale) in Paris. He lit the afterburner and opened the fuel control to the limit. Quickly, the ship accelerated past Mach 2 (twice the speed of sound). The F.A.I, specifies that an airplane trying for a straightaway, level-flight record must not climb or dive more than 164 ft. over the course. To respect these narrow limits at better than 1,500 m.p.h. is quite a pilot's trick. Admitted...
...104C did the work, but Captain Jordan contributed importantly by flying a perfect profile. At 39,800 ft. he kicked in his afterburner and accelerated to Mach 2.36, which is close to the F-104C's maximum permissible speed at that altitude. Then he nosed up at an ideal 47°. At 40,000 ft. he dumped his cabin pressure, and his pressure suit inflated. His afterburner went out at 75,000 ft. He shut off his air-starved engine at 95,000 ft. The ship coasted up without power and porpoised over at 103,395 ft., beating...
...advantage over missiles: it can be recalled, recovered and redirected, can seek out mobile ground targets, and if it misses them, come back to fight again. But the Valkyrie's futuristic design embraces qualities far beyond the capabilities of a mere manned weapon. At its Mach 3 speeds and ultra-high altitudes, it makes an inexpensive, i.e., retrievable, launching platform for earth satellites: it could give the space-probing Xi$ a flashing running start, or fire a 9,500-lb. payload into a 300-mile orbit, or even substitute as a first-stage launching vehicle for the man-carrying...
...J.P.L.'s men are dealing with forces and conditions no man had dreamed of only a few years ago. This week it unveiled a new wind tunnel that pushes the air at the fantastic rate of Mach 9 (6,670 m.p.h. at 32° F.). It will be used to test the shape of future rockets...
MCDONNELL AIRCRAFT CORP. will get new contract for more than $100 million from Navy for Phantom II jet fighters, a carrier-based supersonic (Mach 2 plus) plane...
