... When the missile exploded, the expanding debris cloud from the vaporized weapon was probably moving faster than the speed of sound. Even so, in this second picture you can see none of it had touched the plane yet when the shot was snapped. Yet look at the plane: it’s on fire. How can that be?

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.
