...watched the firing, pronounced the test "an unmitigated, unqualified, unequivocal, unadulterated success." Such strong language does not match NASA's traditional coolness toward solid-propellant boosters. Its ambitious Apollo program to land men on the moon by 1970 is based on North American's liquid-fueled F-l engine, which generates only 1,500,000 Ibs. of thrust. Five Fls will have to be clustered together to boost the Apollo rocket off the ground...
...F-l is reported doing well after five years and $289 million of development cost, but it has not flown yet; and even more money and time must be lavished on it before a cluster of F-1s can be considered a safe enough booster for the ride to the moon. Thiokol's 156-in. motor, twice as powerful as the Fl, worked the first time. Its development cost was only...
...muscle of the actual moon voyage will be the F-l engine now being developed by North American Aviation, 'Inc. Each F-l will have 1,500,000 lbs. of thrust, and a cluster of five will lift the great moon-bound rockets off the ground. But the F-l also vibrates, sometimes so violently during static tests that it threatens to explode. North American believes that the trouble will soon be licked, but this is a lonely confidence...
AERIAL BUS will be built by ex-T.W.A. President Jack Frye in hopes of finding the long-sought-for replacement to the Douglas DC-3. Frye's projected high-wing, four-engine F-l will probably be built by a European company, sell for $350,000, haul five tons of cargo or 50 passengers at an aerial snail's pace (150 m.p.h.) but be able to use a very short runway...
