Personally - Zilch Also - and I used to be a BP refueller. (As well as dogsbody / instructor etc etc )
However, a 'Mooney' was destroyed by fire many moons ago, at Mount Magnet, WA, I think, when the pilot used a plastic container to transfer fuel into the aircraft.
Nil 'earthing' leads.....
The static electricity generated by the splashing fuel and the different 'potentials' of the plastic container & the aircraft caused a spark of sort, and all that was left was the shape of the aircraft on the ground......
Oh Dear.
2 or 42 extinguishers would not have helped this one.
I heard that the pilot suffered some burns as he got the original 'whoosh', but survived OK.
However, the aircraft was a 'trade in' for another....whooops.....
Cheers
