...whose accuracy and judgment are as yet superior to those of unmanned vehicles. Last week the Air Force announced that it would contract with Los Angeles' North American Aviation, Inc. for development of the WS (for weapon system) -110A, an intercontinental bomber hopefully designed to fly at Mach 3 (three times the speed of sound) at altitudes ranging to 125,000 ft. The so-called "chemical bomber" will use not the ordinary fuels such as kerosene and gasoline but materials probably composed, in part, of boron, an element of the familiar household cleansing chemical borax...
...broke the east-to-west record (despite 40-to-150-m.p.h. head winds) in 3 hr. 34 min. 8.8 sec. When he blinked past his home base, Sweet clocked a round-trip record-6 hr. 42 min. 6.7 sec.-averaging 721.9 m.p.h. For the trip he was well above Mach 1.0 (the speed of sound), and at several points along the way he cracked through a ground speed of a little more than 1,000 m.p.h...
...William F. Knowland, 49, stepped into an F-100F Super Sabre jet at Los Angeles International Airport for an invigorating supersonic flight, whizzed along over the Southern California desert at more than 1,000 m.p.h. to break the sound barrier, smilingly received a certificate of membership in the exclusive "Mach Buster's Club." Scheduled for this week: a Sacramento press conference at which every Californian from Governor Goodwin Knight to MGM's Leo the Lion expects him to announce his candidacy for governor...
...hope, nevertheless last week jockeyed a pencil-nosed, silver-painted Navy F8U1 Crusader jet from Long Beach, Calif, to New York City for a new coast-to-coast record of 3 hr. 23 min. First to span the nation at supersonic speed, Pilot Glenn averaged 726 m.p.h. (or Mach 1.1 at his average flying altitude of 35,000 ft.), cut 21 minutes off the previous record established in March 1955 by Air Force Lieut. Colonel Robert R. Scott in a Republic F-84F jet. A pathfinder jet kept Glenn alerted to weather ahead. Three times-near Albuquerque, Olathe, Kans...
Showing it off last week at Fort Worth, Texas, Air Force officers happily hinted that the Hustler's performance was forcing a flurry of tactical recalculations. It has flown at Mach 2-twice the speed of sound (Mach 2 at 40,000 ft. is 1,300 m.p.h.). A few ultramodern U.S. fighters may be faster in short spurts, but they would have trouble climbing from the ground in time to catch a Hustler at high altitude. Supersonic F-102 fighters must use their afterburners, at heavy cost in fuel, to stay anywhere near it. Even many rocket-pushed missiles...
