There are quite a few ground witnesses, that reported an expolsion/fire right before the pieces falling off/crash.
Hate to say this, cuz I'll get razzed, but where is Michael Rivero? His input may be helpful. He can think 'outside the box', and he seems pretty knowledgeable about things like this. Remember, he's our resident 'bulldog' who wouldn't let go of the deliberate downing of TWA 800.
Yeah, but that "box" is reality.
