Who Says Sonic Booms Can't Be Seen..., See it to believe it.
Of course they can be seen.

There is an idiot in a forum I frequent who says we can't see it. Guess he is eating his words now.
Anyway can some one tell me what exactly happened to cause it to blow up in the end ? fuel tank rupture due to strain?
Yes, it's very hard to se it, but that doesn't mean that it's impossible... The fact is that it happends in a split second, wich means that it's very hard to notice, but for a well-trained eye it shouldn't be a problem... Now, how do you think they got the boom on the picture... They had to know when to press at the "picture taking button".... besides, I have seen many videos where this bbom is being shown, with out slow motion...

Those aren't sonic booms. Unless a P-3 can go supersonic, because I've seen the exact same effect around a P-3 Orion, and they are DEFINATELY not supersonic planes. Those planes are in the transonic range, shortly before going supersonic. The fighters are still accelerating which is why it happens so close to going supersonic.
If the original video is the one I think it is, they had just replaced the engine, and were doing a functional test flight to verify if it worked, and when they went supersonic, the engine exploded.

this is a tomcat breaking the sound barrier, i hope no ones posted it yet

It's the exact same thing. If you watch all of these pictures, they're out over the ocean. The humidity in the air causes it. It's just before they break the sound barrier.
"Because these clouds tend to be seen when the aircraft flies at near-sonic speeds, it is frequently said that they "visualize shock waves" or are due to the aircraft "bursting through the sound barrier". Neither statement is true, although the second at least suggests that the phenomena occurs in the near sonic or, in the language of aerodynamics, transonic, regime. The point of this page is to give a short, non-technical discussion of the physical origins of this phenomenon.
The clouds appear for the same reason that clouds always form, namely, that the air has cooled to the point that the ambient water vapor condenses. Flows around bodies and wings always change the temperature and pressure of the fluid. It is well known that lift is caused by pressure differences on top or bottom of a wing or body so that it ought to be obvious that the pressure varies from point to point in a flow around an object. The fact that the temperature changes can be seen by noting that most fluid flows and nearly every aerodynamic flow are frictionless. In the language of thermodynamics, the flow is said to be reversible or loss-free. As a result the entropy of the flow is a constant and the temperature (T) at each point in the flow is necessarily related to the pressure (p) as follows:"
