I should explain: I don't know if there was explosive residue found/covered up/discovered by sniffer dog which was later murdered by Bill Clinton - or not.
I don't know if the plane actually suffered an explosion in the fuel-tank area, or if it folded up like an accordion after losing both wings.
I'm just challenging this "heat-seekers must hit the engine" idea, which I believe to be a chimera.
But to me at least it makes sense that it would. From miles away, the engines are the biggest heat source the airplane was putting out. That's what the missile seeker would have locked on to and tracked to. And I suggest the lack of any evidence of an explosion, either on the engine or outside the center fuel tank, also is an indication that a missile wasn't the cause.
