Cruise missile test

Check out this 1986 test of a Tomahawk cruise missile. (with a hat tip to the Bad Astronomer)  Phil points out that, even though the explosion is moving faster than the speed of sound, the plane has burst into flames before the explosion has reached it.  He goes on to explain, "When the warhead exploded, it sent out a huge pulse of heat in the form of infrared photons, light that travels about a million times faster than sound."  And being  scientific and all, he relates this to asteroid deterrence.  Follow the earlier link for more discussion and another photo.
