Since 1985, the Safety Board has investigated or assisted in the investigation of two other fuel tank explosions involving commercial transport-category airplanes The most recent accident 'nvolved a Philippine Airlines B-737-300 at Ninoy Aquino International Airport, Manila, 'hilippines, on May 11, 1990. In that accident, the CWT ullage' fuel-air vapors exploded as the airplane was being pushed back from a terminal gate, resulting in 8 fatalities and 30 injuries. The ambient temperature at the time of the accident was about 95T, and the airplane had been parked in the sun. Although damage to wiring and a defective fuel quantity sensor were identified as possible sources of ignition, a definitive ignition source was never confirmed.
The Safety Board also assisted in the investigation of the crash of Avianca flight 203, a B-727, on November 27, 1989 The airplane had departed Bogota, Colombia, about 5 minutes before the crash. Examination of the wreckage revealed that
a small bomb placed under a passenger seat, above the CWT, had exploded The bomb explosion did not compromise the structural integrity of the airplane; however, the explosion punctured the CWT and ignited the
fuel-air vapors in the ullage, resulting in destruction of the airplane
Earlier, the Safety Board conducted a special investigation of the May 9, 1976, explosion and in-flight separation of the left wing of an Iranian Air Force B-747-131, as it approached Madrid, Spain, following a flight from Iran Witnesses reported seeing a
lightning strike to the left wing, followed by fire, explosion, and separation of the wing...
In a fuel tank, the ullage is the vapor-laden space above the level of the fuel in the tank.

Thank you Singlecoil. You didn't mention the fact that Boeing has had center fuel tank explosion issues for years. Phillipine Airlines had one on a 737-500, and the Air Force had several on the KC-135, including a couple in flight.
No doubt somebody will bring up the voliatility of JP4 vs. Jet A. Sorry, but you'll have to make a different arguement.
Again, time to ask which is more likely:
Dozens if not hundreds of professional military, law enforcement, and trained accident investigators, board members, all sworn to finding out the truth and or following the rule of law have remained silent. Each and every one of them. The Government, which brought you Watergate, Vince Foster, Monica Lewinsky, Randy Cunningham, and so, so, much more, got it right. Every single detail in place. Nobody speaking out.
OR
Yet another Boeing Jet is destroyed by a center fuel tank explosion.
WHICH IS MORE LIKELY?!
Any of you link posters care to answer my question honestly?
