...rocket (about the weight of a Delta rocket), McDonald proposes to use a steel tube 8 ft. in diameter, 1,160 ft. long, anchored vertically in the sea. At the bottom, a door that keeps water out will open only when the pressure inside exceeds 500 lbs. per sq. in. The rocket will be suspended just above a mass of auxiliary fuel at the bottom of the tube. The top of the tube will be closed by airtight doors, and most of the air inside will be pumped...
When the rocket is launched, its engine and the auxiliary fuel will be ignited at the same instant. The trapped combustion gases will produce a pressure of 500 lbs. per sq. in. that will drive the rocket upward with 3,600,000 lbs. of thrust and about 35 Gs of acceleration. It should reach the end of the tube in 1,205 sec. Air pressure will open the doors to let it pass, and it will pop out with the respectable speed of 1,000 m.p.h. Only 2,500 lbs. of its own fuel will have burned, and it will...
Memphis to South America. The cargo that today's rivermen supervise is often exotic: wine gurgles along in stainless steel tanks, and other specially designed barges carry molten sulphur at 280°, methane chilled to -258°, and chlorine under 250 lbs. of pressure per sq. in. The Saturn missile stages designed to travel faster than sound move in and out of Huntsville, Ala., by river...
...conditioned building to 64-ft.-long tractor-trailer vehicles called transporter-erectors (T-E's). These crawl at 15 m.p.h. on level roads, stall to 2 m.p.h. on grades. The 150 silo sites of Malmstrom's 341st Strategic Missile Wing are scattered over 18,000 sq. mi., connected by 3,000 miles of road, only 500 of them paved. At the sites, the TE's raise the birds, slide them gently into place...
...sprawling, empty land consisting of 615,000 sq. mi. of desert and steppe, lying between Russian Siberia and Red China, Outer Mongolia first showed its loyalty to Moscow by roundly condemning China's stooge, Albania. The Mongols went much farther last year, when Luvsantserengiin Tsende, the No. 2 Communist, charged that the "deep moral decay of the Chinese Communist Party" was evidenced by Peking's "groundless and malicious attacks on the Leninist party and the Soviet Union." In taking a hard line against Peking, Outer Mongolia was taking desperate chances, since its territory is surrounded on three sides...
