Allow me.
CWT is the acronym for CENTER WING TANK.
The official finding was that the CWT exploded due to ignition of the leftover fuel by some point source. (so this isn't exactly a lie, if you consider the point source may have been ROCKET).
As far as reason to reject the official findings, here is one. If this had been true, the FAA would have grounded every boeing aircraft of that make/model. They didn't.
The Federal Aviation Administration (FAA) has ordered airlines to shut off fuel pumps on Boeing 737s when there is a low level of fuel remaining in the center tank.
Fuel tanks have been blamed for an explosion last month aboard a Thai Airways Boeing 737 and for the 1996 destruction of TWA Flight 800.
The FAA's action on Friday comes four years after the National Transportation Safety Board made a similar recommendation following the TWA Flight 800 crash.

And the foregoing is precisely my point. For every question raised, there has been an "official" answer. Until you can PROVE missile or bomb all this is all just suspicion.
