Hi Mr G,
Interesting question, ... but I think for the hydrocarbons to ignite there would have to be oxygen present, even at that high temperature, but you would think they would have to be careful.
Now I think I understand why Angus Edgar said they would press the start button "carefully" !
It could end up something like, "Beneath Hill 60" :)
Still, that would be a good question to ask of RER.
Regards, Ravi
