Continuous Replacement. Russian-built MIGs have accounted for another 20 planes, a poor showing against the 72 MIGs that U.S. pilots have downed in dogfights and another dozen or so destroyed on the ground. In the last month alone, the U.S. has destroyed an estimated 25% of the North Vietnam ese air force, bringing its total number of planes down to some 85 or 100. Since Hanoi never had more than 125 planes to begin with, and well over half that number have been lost in the war, Russia obviously is providing new planes to make up for at least...
...many planes compares in military aviation only with the Luftwaffe's own horrendous record in the late 1930s, when it lost 572 aircraft in 1938 alone, including the mass crash of 31 Stuka dive bombers that blindly followed a flight leader through the clouds and smack into the ground...
...almost effortlessly along smooth highways and waterways at automobile speeds, even the most powerful could not rise more than a foot above the sur face; the air curtain could not effectively contain pressurized air above this height. As a result, hovercraft could not operate over choppy seas or rough ground, where they might smash into jutting rocks or wave tops...
Transatlantic? By 1963, British engineers had solved the clearance problem by equipping hovercraft with rubberized canvas skirts several feet long. Although the skirts were strong enough to contain the pressurized air-enabling hovercraft to rise several feet above the ground-they were flexible enough to brush over solid obstacles and high waves. The development of skirts converted the hovercraft from an experimental device into a practical means of transportation. The British Hovercraft Corp. has already built and sold seven-ton, 18-passenger hovercraft and nine-ton, 38-passenger models like those in operation at Expo 67. Both have...
Renovating Islam. Potentially, the most fruitful ground for discussion, ecumenists suggest, is not theology but the search for common religious solutions to pressing worldly problems. A notable advocate of this approach is the Benedictine monastery of Toumliline, in Morocco's Middle Atlas mountains, which for eleven years has sponsored annual meetings of Moslem and Christian thinkers from dozens of countries. The sessions deal broadly and impartially with major contemporary themes, such as the problems of youth and cities. Purpose of the meetings is to encourage Islam to face these issues from the perspective of its own traditions. Says...
