Sounds like the story I read in Air Clues from either the very late 80's or very early 90's. ISTR he was left with the option of stay put or open the door and try to run through the inferno, somehow he made it
I think the article went into detail on the injuries suffered and how the AEA performed, I remember it convinced me to always wear 2 full layers.
Tried finding a reference to it on the web but no luck I'm afraid. It's a shame that no one has put all the Air Clues articles on the web.
