...spirals and then attempted artificial insemination. A control group of 21 cows averaged 1.8 services per conception; all the protected 18 remained infertile during a series of 42 services. News of the results has been optimistically received by the Indian Ministry of Food and Agriculture, and plans for a pilot project are under way." Scientific American, January...
...young, green kids, and there was a lot of flak around." Because of mountainous terrain, the U.S. jets usually must attack low, slowly, and in single file, which makes them all the more vulnerable; it was only last November when a jet fighter was shot down and its pilot killed...
...much propagandizing for the operation as they are trying to break down prejudices against it. One area where there is an active campaign t. promote it is Appalachia, where men who have been unemployed for years continue to father unwanted children. The Voluntary Sterilization group has set up a pilot project for several countries,* with a $25,000 grant from Jesse Hartman, a Manhattan real estate man. In its first six months, this plan has signed up scores of men and women, with 115 operations already completed or approved at an average cost of $195 for women...
Novel Control. At 10,000 ft. over Carswell Air Force Base near Fort Worth, Test Pilot Richard L. Johnson began the critical maneuver that is the F-111's reason for being. In the instrument-crammed cockpit, he reached for a novel control: a pistol grip that can be moved backward and forward like a trombone slide. He pushed it forward, and the wings responded by folding backward. He moved them first to 26 degrees of sweep, then 43 degrees, at last to 72 degrees. In this highspeed condition, the F-111 looked like a schoolboy's folded...
...flight, the F-111 climbed to a modest 27,000 ft. and flew at only 450 m.p.h., which is less than one-third of its planned 1,650-m.p.h. speed. But the revolutionary wing mechanism worked perfectly, and the airplane handled easily with wings in all positions. Before landing, Pilot Johnson pulled the trombone control backward. The wings extended again, and the plane touched down lightly at moderate speed. Many more flights will be necessary, but the crucial wing-sweeping maneuver was wholly successful, and it was completed 24 days ahead of official schedule...
