...contest will afford display of an encyclopedic range of talents. There will be four categories of judging: for the stayers, duration aloft; for the ambitious, distance flown; for the showy, aerobatics; and for the aesthetes, Origami (Japanese paper-folding...
What would happen if the MIGs suddenly swarmed aloft in numbers and became more aggressive? "We would simply have to do more of what we are doing now," shrugged one Air Force spokesman in Saigon.

But if air opposition reached the point where U.S. planes were constantly forced to jettison their bombloads in order to defend themselves before reaching their targets...
...using an ion engine instead of chemical fuel for deep space acceleration, Stewart believes, scientists will be able to launch outer planet probes with rockets as small as the Atlas-Centaur, or send considerably larger payloads aloft with the Saturn 5. Combined with gravity assists from the planets, the ion engines should allow sophisticated unmanned probes to give man a close look at the outer planets, regions outside the solar system - and even the sun itself...
...lengthy space flights, fuel shortages may force astronauts to cut their missions short. But as long as they are aloft, there is little chance that there will ever be a shortage of one constant byproduct of manned-space missions-human waste. During a three-month flight, for example, a crew of three will produce approximately a quarter-ton of solid wastes. What to do with it? Seattle's Rocket Research Corp. offers a practical answer: process the waste and use it as a source of rocket fuel...
