...thought, 'That's the last time I'll walk in with the trumpets and the pomp.' It gives one a little sense of mortality." With help from on high, a cathedral under construction in Britain got a finishing touch. At Coventry Cathedral, a twin-rotor helicopter picked up a two-ton, Soft, spire, flew the length of the church's copper-covered concrete roof, hovered dead on target while builders bolted the spire into place. Supplier of the helicopter: the Royal Air Force, whose outnumbered pilots had to watch helplessly one night 22 years...
...ahead of Moss going into the first turn," said Fireball sadly. "But I came in too hot and went wide. Moss passed me, and from then on it was adiós. I never saw him again." Stocker Weatherly also had a run-in with Moss: a broken distributor rotor forced him to slow down, and Moss impatiently nudged him off the course. "I don't think he meant anything by it," said Weatherly. "I just got in his way." An easy winner in the G.T. division, Moss picked up $7,500, and Ferrari picked up nine points toward...
Horse-Collar Rescue. Whatever the cause of the mishap, the next few moments were hectic. One helicopter tried to snap up the Liberty Bell 7. The second could not come too close to pick up Grissom because of the rotor blast of the first. So Grissom swam 25 yards to a calmer spot, where the second helicopter lowered a "horse collar" and lifted him out of the water. Hurried back to the Randolph, he made his first remark seconds after stepping aboard: "Give me something to blow my nose. My head is full of sea water...
...fuselage is usually just a tangled trellis of thin steel tubing. The cockpit is an open bucket seat, bolted prayerfully to the frame. The power plant is a sputtering, 40-h.p. engine borrowed from a motorcycle. Hovering motionless in midair, its 10-ft. rotor blades windmilling, the makeshift craft looks like an airborne Erector set. But in the hands of an experienced pilot, it can fly like a startled mosquito-straight up to 8,000 ft., forward, sideways or backward at 65 m.p.h., right down to a feather-soft landing on any convenient driveway. Last week, in a dozen...
...Pound Per Year. The chief trouble with the early centrifuges was their comparatively slow speed. This was serious because their effectiveness in separating U-235 rises with the fourth power of the speed of the rotor, i.e., doubling the speed would multiply the efficiency by 16. Better materials and construction methods have recently increased the speed to at least 40,000 r.p.m. Up-to-date centrifuges spin in a near vacuum, and they have complicated heating devices to make the gas circulate inside them in a way that multiplies their efficiency...
