Statisticians are rocket scientists? That's right down there with your claim about metallurgists:

This area is covered with dust that rained down from the bottom of the heat shield. since these fractures were spreading while the dust was settling, the dust was vibrated away from the stress joint - this will be obvious to any metallurgist who has ever looked for a stress crack.

It was far from obvious to this one. BTW, in metallographic examination of cracks, there is no "dust". You are perhaps getting "dust" confused with Magnaflux™ and its various incarnations, which perform in just the opposite manner.
From what you've been posting, it would appear that this "community" you refer to exists only in a rather fantastic place.
How about dropping a few names to establish some credibility?
