...flying turbine blade had caused the wing fuel tanks to explode, since the last Comet to crash had special armor between engines and tanks (TIME, March 22). Most think it more likely that either the kerosene-type fuel, which becomes highly volatile at high altitudes, exploded, or that vapor from a leaking hydraulic line might have been touched off by a spark. Others guessed that the big jet's power-operated controls, which give the pilot no "feel" of the plane, might have let him accidentally put the ship into a maneuver that ripped off the wings...
Beautiful Thyangboche was where they made their First Base Camp. Towering above was the Everest trinity: Lhotse (27,890) and Nuptse (25,680), joined by a razor edge; beyond, Everest itself, plumed in a wisp of vapor that streams from the summit at 29,002 ft. The three giants together enclose a vast glacial basin known as the Western Cwm (a Welsh word that rhymes with tomb). This was the key to the climb...
Miller set up a closed apparatus containing water, methane, ammonia and hydrogen. When the water was heated, its vapor circulated the other gases past a small electric "corona" discharge, which promoted chemical reactions among their molecules. This sort of thing may have happened on the primitive earth, where lightning was probably common. In any case, the influence of the electric discharge was similar to that of the strong, solar radiation beating down on the top of the primitive atmosphere...
...which the air has so little pressure that human blood (temperature 98.6° F.) begins to boil. If something had gone wrong and Wing Commander Gibb had been exposed to the pressure outside his cockpit,' his veins and tissues would have puffed up with a froth of water vapor, his spinal fluid would have begun to beil, and he would have died in a few seconds...
...last week, a grizzled veteran with eight kills and four rows of ribbons, Low took off from his interceptor base near Seoul. Over northwestern Korea, he and his wingman saw contrails (vapor trails); then Low spotted two MIGs, camouflage painted in green and brown. The enemy planes tried to get away, one zooming, the other diving. Low chased...
