A few years ago I was visiting a customer at a company that does aircraft interiors. He showed me a couple of videos of interior fire tests. One showed the fire retardant they treat the material with. He was holding a piece of cotton cloth, sprayed it with the cloth treatment then took piled on a bunch of magnesium shavings. This was lit with a torch. He shook the rag and there was no holes burned in it. Magnesium burns at about 4000F and he was holding it in his hand.

The second test showed the fire suppresion system. It was amazingly quick at putting the test fire out, but the smoke was intense. Of course this only works on the fires on the inside it couldn't handle a fuel fire.

Like many of the others I make sure to keep my footwear on during takeoff and landing. I try to stick to leather shoes. I also do a quick row count.

I definately would not grab a rollerbag out of the overhead compartment. That is far too dangerous to everyone. I would most likely grab my day bag from under the seat though. On rough landings I have thought about the camera that I normally travel with and the shots I could get after clearing the slide.
