Typing in caps and repeating silly questions does not cover up the fact that your last post was essentially a lie. Furthermore, aviation history is absolutely full of accidents caused by unique events. Using your logic, the cause of the Alaskan Air MD-80 crash off the coast of California couldn't have been caused by the jackscrew in the rudder, because despite decades of flying by hundreds of similar aircraft in airlines around the world, such an incident had never happened before, and hasn't happened since. But to answer your question, there have been two 737's that exploded due to overheating in their centerline fuel tanks. The last was in 2001. In addition, the Air Force had already identified overheating in the centerline tanks of its 747's as a problem years before TWA 800 exploded. And exploding fuel vapor in fuel tanks has been blamed in 9 incidents since 1958, nullifying the often posted theory that jet fuel vapor isn't explosive.
Jet fuel is not flammable under the pressures and temperatures in jet fuel tank.
And as long as you saw fit to call me a liar, I will call you a liar for saying that jet fuel is flammable except under extreme pressure and temperature.
Show me the links to your evidence. Surely you have some.
