Whereas, if you declared an emergency, they could have the fire trucks strung out down the runway, and a helicopter hovering, and maybe get the fire out before it even gets lit.

It's only a matter of seconds for you to go from a flash burn, like a sunburn, to a second, third, or fatal degree of burn.

So as they say in the Navy, when in doubt, call them out.

But if you declare an emergency, don't feel that you have to crash. The crews don't mind a dry run and enjoy racing down the runway with lights flashing and sirens screeching and they would rather stop the fire from starting.
