Gasoline and fires are nothing new to me. We were the kids that got in trouble for burning all of the gasoline in the shed before the grass got cut. Molotov cocktails were old hat by the age of ten or so. I have seen countless fires set with gasoline. This is not your grandpa's gasoline.

I think the ethanol explanation sums up what I experienced, oxygenated fuel. Accelerating burn, there was an oxidizer involved.

I know the wump, this was a boom.

Seriously, don't assume that your lifetime of experience will protect you.
