Quick and quiet: Supersonic flight promises to hush the sonic boom

The Bell X-1, piloted by U.S. Air Force Capt. Chuck Yeager, reached 700 mph on Oct. 14, 1947. At Mach 1.06, it was the first airplane to fly faster than the speed of sound. But at speeds greater than Mach 1, air pressure disturbances around airplanes merge to form shock waves that create sonic booms, heard and felt 30 miles away.
