2.   Concorde is capable of travelling at supersonic speeds.

3.   All will feature stealth technology and fly at supersonic speeds.

4.   And indeed, Sonic Adventure is very fast, almost blindingly so, with sharp, lush graphics that whip by at something closer to supersonic speeds.

5.   And other Concorde customers have clearly drifted to private business jets, some of which fly at near supersonic speeds.

6.   And when that air hits supersonic speeds it produces small shock waves that create drag.

7.   Asked if the plane was flying at supersonic speed, Hall said he would have more information Wednesday.

8.   Ayers used a computer program normally used to test aircraft and ran calculations through a supercomputer that evaluated configurations of a car moving from subsonic to supersonic speed.

9.   Blackbird pilots had to fly in special suits because of the heat created by flight at high supersonic speeds.

10.   A shock wave is a pressure disturbance that builds up around the craft flying at a supersonic speed.
