...uniform by the end of the year would be met. There were 55,570 men already under arms, and recruits were pouring in at the rate of 4,500 a week. As fast as the Germans could accept them, U.S. tanks, self-propelled guns, 90-mm. antiaircraft guns, heavy machine guns and electronic equipment were rolling into German camps, part of a total $1 billion worth which the U.S. is giving the Germans to equip six of their scheduled twelve divisions...
...bumpiness of low-level air would keep it from making a steady bombing run. But it flies pretty fast nevertheless, and if it is flying at 500 m.p.h. (733 ft. per second) when the bomb is released, the bomb starts its curve with the muzzle velocity of an 81-mm. mortar shell, whose range is two miles...
Supersonic Gatling Gun. Designed to kill in the split-second world of supersonic aircraft, a 20-mm. cannon that spews 8,000 shells a minute was announced this week by General Electric, co-developer with Army Ordnance of the gun for the Air Force. The cannon, nicknamed the Vulcan, has six rotating barrels that fire in succession, is patterned directly after the hand-cranked rapid-fire gun invented in 1862 by American Richard J. Gatling and used in the Spanish-American...
Mach 2. By any standard the Crusader is a hot plane. It packs missiles and fast-firing 20-mm. cannons, has a 1,000 mi. combat range, a service ceiling of 55,000 ft. Its top speed with a Pratt & Whitney J57 engine (more than 15,000 Ibs. of thrust with afterburner) is close to Mach 2 (1,320 m.p.h. at 30,000 ft.) in level flight. What helps make such speed possible for a carrier plane is the Crusader's stubby, sharply swept wings: they are ingeniously hinged, can be tilted upwards to act as enormous flaps...
...know who wrote the April 16 review of The Bold and the Brave but I would like to express my profound gratitude for it ... The idea for the movie came about when a young producer friend of mine was showing a 16-mm. film history of the 34th ("Red Bull") Division, and I saw my own tank destroyer in action in Italy. I got very excited and decided to write a war story. I will be grateful my whole life for such a profound, incisive and very beautifully written analysis of what I was trying...
