Jet fuel is pretty heavy stuff, it is not gasoline. For it to produce fireball you have to mix it with air, that means that the explosion needs enough force to vaporize the fuel. We are talking about a bomb of size one could bring on board of the plane. Yes, a 10kg device in cargo hold could probably vaporize both the fuel and the pilots, but this is not your typical airliner bomb.Terrorist on board has weapons to take out pilots and bomb(s)/ suicide vest to detonate etc
Would explain fireball and no communication from pilots
Or bomb explodes and takes pilots out at same time as starting fire in plane
Fact is, even fatal bombing of the plane is very unlikely to produce a fireball, because terrorists want the bomb to be small to be easily hidden/smuggled, and one does not need a fireball to totally destroy a plane. Small bomb that causes just enough structural damage to sever control lines or make large enough hole in the fuselage.
You are stubbornly referring to explosions as seen in movies. Real life explosions are NOT like that.To produce movie effects, large amounts of fuel (e.g. gasoline in plastic bags) are placed next to small charges, which are enough to destroy the bags and spray the fuel around. This then gives a "movie fireball".
But in reality, bomb detonations basically never produce fireball, because detonation is completely different process from burning. All energy that would go into fireball heat and light would be wasted energy, as it would not contribute to the destructive force of the detonation.
So, the only way that explosive device in the cabin/cargo hold would produce fireball is if it is either well placed to target fuel tanks, or it is large enough that its shockwave or shrapnels penetrate fuel tank, with enough energy to disperse enough fuel for a fireball. "large enough" and "filled with shrapnel" is something even the worst airport security in the world would detect if you try to take it on the plane.
Missile, on the other hand, has all the ingredients: sufficient charge (much more than what anyone could hope to smuggle on board) and shrapnel.
Gasoline and jet fuel only weigh .8 pounds different
He's talking in the sense that jet fuel requires much more energy to burn than gasoline. Gasoline has a much higher vapor pressure than Jet A. Gasoline is much more volatile than Jet A. Here's a link for further reading on the characteristics of jet fuel if you're interested.
