...Denver, Farm Editor Partridge thought he had a way. He flew to Oklahoma City (with a Post photographer), bought 15 lbs. of axle grease, and arranged for a veterinary to meet him at Mach...
Scanning the news services, Farm Editor Partridge read about a freak farm accident in Yukon, Okla. An angry 1,200-lb. Hereford (nicknamed Grady by a reporter) had charged Farmer Bill Mach. When Mach prudently sidestepped, Grady kept on going, right through a small feed-door (about the size of a Denver Post front page) in the side of a silo. For three days, while Grady placidly munched hay and grew fatter, Farmer Mach racked his brain for a way to get Grady out alive without tearing a hole in his silo...
...Guggenheim centers will not build bigger & better jet engines, nor even try to. Their job will be to push into unknown regions where the jet engineers of the future may want to follow. One project at Princeton will be the study of air behavior at "hypersonic" speeds-above Mach 5 (five times the speed of sound). When wind tunnels are forced to this speed, and a few of them can be, they hit a fantastic difficulty. The air expands and gets so cold that its oxygen and nitrogen condense into liquids. Princeton will study this disturbing phenomenon...
Short, broad wings are good "future practice" in aerodynamics. The NACA (National Advisory Committee for Aeronautics) proved years ago by wind-tunnel tests that the long, graceful wings of bombers are much less efficient above Mach 1 than clumsy-looking "stub" wings. As planes get faster, their wings will probably grow stubbier still until they diminish into something looking like an arrowhead...
...fast will the XF7U-1 go? It is no secret (and the shape itself would be a giveaway) that it was designed to fly considerably faster than Mach 1. Navy Test Pilot Captain F. M. Trapnell, who is putting the XF7U-1 through its paces, said that he has not yet worked it to top speed or top altitude. He expects, however, that it will prove "the fastest of them...
