...sounded like artillery fire rolling in over the rocky desert floor, but the sonic booms generated by the F-104 Starfighters did nothing more than rattle the windows of the 18 buildings spread out over five acres at White Sands Missile Range, N. Mex. The first pass by a Starfighter produced a shock of 4 Ibs. per square foot of overpressure.* Another boom was boosted to 6 Ibs. per square foot, and subsequent booms raised the overpressure to as high as 10 Ibs. per square foot. But nothing broke. Officials of the Federal Aviation Agency began to break...
...Bogota, at the annual meeting of the 93-member International Air Transport Association-which the normally secretive outfit opened to the press for the first time in 20 years-airmen sounded sorry that they had ever heard of the SST. They fretted about sonic booms, expressed reluctance to give up the highly profitable jets that they now operate, and worried about the shattering effect that they fear supersonics will have on their balance sheets. "At $40 million," said Air India's Chairman J.R.D. Tata, "we would be paying five times as much for an aircraft doing only 21 times...
...lengthy ascents they require to reach cruising altitudes, the engineers insisted that the planes will be practical down to flights of only 600 miles, will be able to operate productively for ten hours a day v. nine for the present jets. They held out promise that the sonic-boom problem will be solved eventually, possibly by delaying until high altitudes the crossover from subsonic to supersonic speeds. Most of all, they stressed the inevitability of the SST-a telling argument to an audience that included many whose careers date back to the trimotor Ford...
...latest contribution to submarine meteorology was made by modified Swallow buoys,* which are 13-inch aluminum spheres ballasted to sink until they reach water of a selected density. Crammed with apparatus that reports its observations with sonic pings, the buoys can be followed accurately through the depths. They can communicate with each other and measure their distance apart; they can be instructed by a coded sonic signal and told when to drop ballast, rise to the surface, and call by radio for pickup...
...plane has so far got exactly nowhere. Now the big argument seems to be whether it is really practicable in its proposed form. Aviation Consultant William Littlewood recently told a Washington aeronautical conference that ground dwellers cannot adjust to the SST's shattering sonic boom, suggested "careful routing" of the planes at a cost in time and fuel. Last week Clarence L. "Kelly" Johnson, the Lockheed vice president who designed both the U-2 and the A11, said as he received an achievement award from the National Aviation Club: "I am very concerned about the sonic boom where...
