That's not what I said. The only time that you would get a combustable mixture is when the tank is pumped "dry" (notice that "dry" is in quotes). The pumps leave some residual fuel in the tank and it takes that very low quantity of fuel, along with high temps, to produce a combustable mixutre. When there is more fuel in the tank the fuel/air mixture is too rich for combustion.</font>
So if they hit a plane on take off, even if they did puncture the tank, it wouldn't do all that much, correct?
From what you are saying, the time to hit a plane if you wanted a fireball would be on landing, when the tanks would be less full and there would be the potential for a fuel-air mix that's right for combustion.
