I can't vouch for the missile theory, although I believe the aircraft was blown apart by an outside induced explosion, vis missile or with internal plastic explosives, etc. attached to the center fuel tank. I can vouch for the integrity of the center tank fuel system on the B747. No technical "expert" will ever convince me that the explosion was caused from the malfunction of wiring inside the fuel tank.
Well what could cause the center fuel tank to suddenly explode? We already have the answer and its completely consistent with an AQ stile attack, low cost and simple, a shoe bomber sitting directly over the center fuel tank. I believe the explosive residue was suppressed not so much to cover Clintons butt but rather the airline industries.
