Every photo that I have seems shows the open roof. I can't tell if the fire burned it through or if the roof was ripped open by the fire fighters and the rescue teams.
If the former, I wonder if the plane's vertical profile was designed in such a way as to keep the fire above the passengers (if such a thing is even possible).
My experience with fire in an enclosed space is that you never want to introduce air. I am confident that the airport fire crews did not rip the fuselage open at the top. The photos I have seen look like burned aluminum. http://a57.foxnews.com/global.fncstatic.com/static/managed/i...
