Yesterday I finally got my chance with the fire. A shed with gasoline (or some kind of fuel) seeping into what used to be an airline chair was where I had my debut as a firefighting machine!
I cried out "I have a fire in the overhead bin! Inform the captain and get me backup!", tore off that witness wire, whipped out that pin, aimed at the base and swept that extinguisher side to side with gusto! I then slowly backed away, never once turning my back on the now smouldering seat frame.
It was a rush (though slightly less exciting than I had hoped). Hopefully I won't forget what to do when/if the time ever comes! I think someone may have gotten a picture, so if I ever get my hands on it, you KNOW I'll be showing you!
So if you ever have any fires, just call me up and I'll be right over, because I am now trained with LIVE firefighting!
