TWA Flight 800: A tale of two reports and conclusions

A new documentary on the crash and investigation of TWA Flight 800 re-igniting interest in the cause of the July 17, 1996 crash.

According to ABC News:

In a new documentary, former investigators who looked into the mysterious crash of TWA Flight 800, which killed 230, are breaking their silence to claim that the explosion that brought down the plane in 1996 was likely no accident, and that the final report on the cause of the blast was falsified.

TWA Flight 800 exploded in mid-air on July 17, 1996 about 11 minutes after taking off from New York's JFK airport on its way to Paris. Though theories abounded as to what happened to the plane -- from a bomb on the aircraft to it being struck by a missile or even a meteorite -- the National Transportation Safety Board concluded after a four-year investigation that the probable cause of the crash was an accidental fuel tank explosion.

ABC News's website links to the 2000 NTSB Report on the crash.  The 2000 Report states the cause to be:

The National Transportation Safety Board determines that the probable cause of the TWA flight 800 accident was an explosion of the center wing fuel tank (CWT), resulting from ignition of the flammable fuel/air mixture in the tank. The source of ignition energy for the explosion could not be determined with certainty, but, of the sources evaluated by the investigation, the most likely was a short circuit outside of the CWT that allowed excessive voltage to enter it through electrical wiring associated with the fuel quantity indication system. 

However, here is the July 17, 1998 Interim Report by Commander William S. Donaldson, U.S.N. Ret on the cause of the explosion and crash of TWA Flight 800. Note the summary page (page 5) that states the causes.  Here are the first two:

Notice the difference?

This smells like a cover-up.  Guess who was president at the time?  Bill Clinton.

Why would this be covered up?  Could the disaster be from "friendly fire"?  Or, could it be from an attack by al-Qaeda agents (after all, this did happen a little more than four years before September 11, 2001 and after the February 26, 1993 World Trade Center bombings) that the Clinton Administration did not want disclosed?  Clinton was running for re-election that year.
