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.
Then you ought to apologize, because first, I never said anything about jet fuel. I said jet fuel vapor. Big difference. And here is what Boeing says about it...
"The flammability of the center tank ullage is a function of the temperature of the center tank fuel puddle (a thin layer on the bottom of the nearly empty tank) as well as other factors (e.g., fuel composition). Our analysis of the JFK fuel temperature data (spikes that approach actual fuel temperature), together with data from the Marana test (see below), lead us to conclude that the fuel temperature of the puddle of fuel at the time of the TWA 800 event was approximately 130°F to 140°F. Based on this temperature estimate and the jet fuel test data, we conclude the CWT was well within the envelope to be considered flammable. "
