...with its European competitors over the nature of Lord Montagu's invention. The International Air Transport Association has agreed that airlines may serve only sandwiches on their new cut-rate transatlantic flights v. free full meals on regular flights. Pan American, which still considers the sandwich a thin layer of filling between two slices of bread, charges that European airlines are evading the rule against free meals by serving sandwiches that are actually sumptuous repasts...
...legend itself breaks up into public and private anecdotes, into classroom jokes and conference revelations. The undergraduate who came to know him well usually did so by moving through the larger layer of public acquaintance into increasingly attractive familiarity with the man; discovering Copey first merely by being at Harvard, then by going to a Copeland reading, then enrolling in one of his courses, meeting him in conference, and finally-- if he had proven himself worthy--in friendship, which was itself conducted with enough style to make legends...
When Astrolite is exposed to a blast of high-temperature gas, a thin layer of the plastic on the surface burns off, leaving a mat of silica fibers arranged so that they cannot be easily blown away. At 3,000° F. (about the melting point of iron), they begin to soften, but melted silica is sticky, viscous stuff that clings tight until it turns to vapor. The vaporizing process draws heat from the remaining Astrolite and tends to keep it cool...
...melts at about 450° F.), but it is remarkably successful against short attacks of extreme heat. It is used in 20 types of missiles, sometimes in the nose cones, sometimes in other hot spots such as the nozzles of rocket motors. The Thompson company says that a laminated layer of Astro-lite two-tenths of an inch thick can protect the nose of an IRBM. For an ICBM, which enters the atmosphere much faster, four inches may be needed. This thickness weighs, says Thompson, only one-fifteenth as much as a heat-resistant metal used for the same...
...meets resistance and therefore slows down. Physicist Neuringer's proposal is to create a strong magnetic field on the front surface of the re-entry body. When ionized air flows across it, the braking action of the magnetism will make it pile up in a deeper, slower moving layer that will not transfer as much heat to the solid surface...
