bnt "Has anyone said anything about how much was pouring out?"
Probably the same amount by which it may have been overfuelled. If the a/c was on stand at 2100(L) I doubt thermal expansion would be a major cause, willing to stand corrected though. Given the operator & pax load it's reasonably safe to assume it's a 737 concerned, so the wing tanks were probably required to be at or very near full at least, hence increasing the chances of fuel venting. As for "elitist" comments, the crew who are trained to carry out that task explained it was perfectly acceptable for this to occur, as has been mentioned already they're first to the scene of the accident so why would they risk anything? bnt, music isn't such a black & white affair as this but if a professional musician had explained something contrary to my initial understanding then I'd take their word on it since I don't know better than them, is that not what the other posters were getting at?
