NASA plans to take the boom out of supersonic flight

By Jeff Hecht NASA has completed a delicate set of flight tests to measure how modifications to an F-15 jet can affect the way shock waves form. The results could help turn sonic booms into distant rumbles. The measurements will be used to calibrate a computer model of shock wave propagation which will be a crucial aid for engineers designing a new generation of quieter supersonic aircraft. “We’re pretty close to being able to control sonic booms,” says Peter Coen of NASA’s Langley Research Center in Virginia,
