Eighty minutes later Pilot Claude banked the big DC-6 into line with the twinkling lights of Love Field's long north-south runway, lowered the wheels and wingflaps for landing. Suddenly the outboard right engine sputtered and died. The two good engines bellowed as he poured power to...
Pilot Claude, Copilot Lewis, their flight engineer and 15 of the Aztec's 41 passengers escaped from the white-hot pyre. When the wreckage had cooled, an American Airlines ground crewman stood sobbing as he kept count, in a little black notebook, of the bodies carried from the blackened...
To escape into outer space, Lewis pointed out, requires an initial speed of 6.95 miles a second (25,020 m.p.h.). This requirement cannot be dodged by running the rocket motor slowly over a long period; that would only waste energy by forcing the ship to carry heavy fuel to a...
While hearing this piece of optimism, the A.S.M.E. also honored, as the year's best technical paper by an undergraduate, a piece of rocket-pessimism by George D. Lewis of the University of Connecticut. Engineer Lewis, who now works for Pratt & Whitney Aircraft Co., argued mathematically that a single...
To reach "escape velocity," the space ship's fuel must be used as economically as possible, and the efficiency of a rocket motor depends on the speed of the exhaust gases. Lewis calculated that a space ship carrying half its total weight in fuel would have to shoot out...
