Clark said he agreed with Justice Hugo Black's televised statement that the wording of the Brown vs. Board of Education school desegregation decision was "unfortunate." "By deliberate speed we didn't mean an eternity," he said. "We're human, too--some people think that we're not, that we have horns...
What the Air Force wants is dubbed an "Advanced Manned Strategic Aircraft" (AMSA). Built more like a rocket than a plane, the new bomber would hit a top speed of Mach 2.5 (1,800 m.p.h.) at high altitude on the way to its target. Then, swooping low to avoid detection by enemy radar, it would slow to Mach 1.2 (790 m.p.h.) in the denser air. With a crew of four, it would carry a payload twice that of the B-52 and, with mid-air refueling, would have a range of more than 6,000 miles...
Generating 7,500,000 Ibs. of thrust, Saturn will thunder to an altitude of 38 miles and a speed of 6,000 m.p.h. in only 2½ minutes. Then, having carried out the herculean task of lifting a 3,100-ton, 363-ft.-long vehicle through the thickest layers of the atmosphere, the giant booster rocket will drop away, and the S-2 second stage will take over. With its five engines producing 1,125,000 Ibs. of thrust, the S-2 will accelerate the shortened vehicle to a speed of 14,000 m.p.h. and hurtle it to an altitude...
...pace-2,170 m.p.h. At this point, lunar gravity will overcome the earth's diminishing pull, and the spacecraft will begin accelerating once more. Ahead, the moon will loom ever larger in the spacecraft windows. By the time Apollo curves around the western edge of the moon, its speed will have risen to 5,720 m.p.h...
...tenth lunar revolution, the Apollo crew will fire the SPS engine again-this time for 206 sec. -boosting their speed to 6,060 m.p.h., more than enough to break the moon's gravitational hold and start the spacecraft back toward the earth. About 57 hours later, accelerating under the pull of terrestrial gravity, the astronauts will position their craft properly and then jettison the service module. Streaking into the earth's atmosphere at an angle of 6.5° and a velocity of 24,765 m.p.h., the 11,700-lb. command module-all that will remain...
