Thanks guys....what happens to the fuel dumped? Does it evaporate, does it make it more dangerous for following planes?
I remember a James Bond film where he escaped certain pulverising by turning a hair spray + cigarette lighter into a flame thrower. To answer your question find the clip. With Jet A1 it should be impressive. Guys on the ground will think we've just been struck by an unidentified comet. The UFO brigade would go bonkers; and the ancient alien theorists would treat it as a second coming.
