How TWA 800 was destroyed does not matter. This solution will prevent any future fuel tank explosions, even if the aircraft is hit by a missile.
I must admit, this solution is rather simple and did impressed me.
Use the natural 80% Nitrogen and 20% Oxygen in the air and remove the Oxygen. What you have left is an atmosphere that will not allow aviation fuel to explode, no matter what the cause is.
Interesting technology and I hope that our military aircraft are rapidly upgraded to this new molecular filtration system.
Jet fuel does not "explode" in fuel tanks. Nobody was ever able to make it explode in TWA800-like circumstances. At the very worst, in a very contrived setting, the fuel was set alight and it burned with a flamefront that took several seconds to traverse a scale model fuel tank. This does not even qualify as a "low explosive."
It did not rupture the model tank, though there are some theories that combustion products could possibly raise the pressure in the tank enough to do that. But the tank is vented, so even those theories are hard to support. Nobody has EVER made burning jet fuel rupture a full-scale or scale-model airliner fuel tank.
