Since sound is a mechanical disturbance that propagates through the air, there is a limit to its speed. An object such as an airplane, moving through the air, generates sound.: Tokyo to New York in Six Hours" (Spring '06) incorrectly stated that JAXA JAXA - Japan Aerospace Exploration Agency tested the Silent Supersonic Technology Demonstrator. JAXA tested the Scaled Experimental Supersonic Demonstrator.
