...trouble with liquid-fuel engines, says Ritchey, is their unreliability, which "is a matter of common knowledge to those who read newspapers." It is hard to make pump-fed engines much more powerful than they are now, and "the reliability of a single liquid-fuel engine is so low that even the most optimistic may quail at the idea of grouping more than a few turbopump systems into a clustered stage." Rocket engines using a solid propellant fire perfectly almost every time; they can be used in large clusters with expectation that all of them will do their duty...
...White House for commitment under the omnibus housing act of 1957. The act provided a total of $1,740,000,000 for various home-building programs, a sum that President Eisenhower declared high at the time. With recession causing concern (TIME, Dec. 30), the decision was made to pump the money into the economy. Biggest item: $107 million to help pay for mortgages on armed forces family housing...

The leak produced two quick effects: 1) because an improper ratio of fuel was being pumped into the thrust chamber, the missile lost thrust; 2) escaping fuel spurting against the hot pump assembly caught fire, turned Vanguard into a grounded inferno when the fire backlashed to the fuel tanks.

Many a surgeon dreams of the day when, like the mechanic faced with a worn-out fuel pump, he will be able to dip into a bank of human spare parts and fix up his patient with a replacement for.an ailing organ−even one so vital to life as a kidney or the heart itself. So far, apart from the difficulty of obtaining such spare organs, two obstacles have seemed insuperable: 1) the surgical difficulties of making all the necessary blood-vessel connections in time, and 2) the immune reaction which causes a recipient to manufacture antibodies that destroy...
