...little air, but it is much too thin for an airplane to steer by. So for controls the X-15 will use six small jets of hydrogen peroxide gases shooting out of its tail and wings. When the X-15 is above the effective atmosphere, its pilot will feel zero gravity and float off his seat to the limit of his belts. Loose objects in the cockpit, if any, will drift around like smoke. This condition will last for something like five minutes, ending only when the X-15 meets denser air on the way down...
...which are 7 ft. apart and three times as heavy as railroad rails. They came in 3Q-ft. sections and were welded together on the spot into 10,000-ft. lengths. Merely fastening them to the concrete slab would not do; the temperature of the Tularosa Basin fluctuates between zero and 120°F. If the rails were fastened in cool weather, a hot summer day might make them expand and buckle out of line. So each 10,000-ft. length of massive rail was stretched 3 ft. by hydraulic jacks. At ordinary temperatures the rails are under tension like...
...Blooey" was right. Every one of the major lines serving the Atlantic Coast from Washington to Boston was hard hit.. As drifting snow buried tracks and zero cold froze engines and switches, the New York Central, the New Haven, the Erie and many other commuter lines ran hours late. Trains loaded with commuters got stalled in the fields, and rescue trains sent out after them got stalled too. The New York Central reported its long-haul trains running between New York and Chicago as much as 20 hours late. Each delay produced a paralyzing chain reaction. The day after...
...pressure inside the rocket falls abruptly. The fuel stops burning, and the thrust drops to zero. If this kind of cutoff is not accurate enough, small vernier rockets can be used to give the proper amount of extra push. Or retrorockets thrusting in reverse can shave a few feet per second off the rocket's speed...
...orders so sharply that inventories tumbled $300 million, bringing their annual reduction rate to $3.6 billion. Retailers slashed their inventories so fast that store stocks plummeted $1.9 billion in barely 30 days. On an annual rate, the fantastic cutbacks would reduce U.S. retail stocks (currently $23.4 billion) to almost zero by the end of 1958. As a result of the cutbacks, the Federal Reserve Board industrial production index dropped three points to 133 in January...
