A few thoughts on this thread from the environmental chemist/haz waste nerd:
The cell phone thing has been properly investigated and debunked in my opinion. It still comes up regularly.
I agree static is the biggest danger because the spark can occur where your hand is holding the nozzle, right where the vapors come out of the tank.
I always ground myself if I've re-entered the car, and even the first time I get out in the winter. I use the back of my hand to reduce the pain, either on the car or the pump.
I have no doubt the tip of a burning cigarette is hot enough to ignite gasoline vapors.
Yes, gasoline vapors are heavier than air so they 'should' drop to the ground, but if you've ever smelled gasoline while fueling - like, every time, right? - you'd have to be an idiot to stand there with an ignition source sticking out of your face.
I am not sure what the hydrocarbon range of JP4 is exactly, but jet fuels straddle the gasoline and diesel ranges. They do (generally) overlap the top half of the gasoline range, but they don't have the lighter more volatile end of gasoline. JP8 is specifically a higher flash point product than JP4.
