"A massive fireball rolled through the cabin"
This theme seems to be common to every single aircraft accident that doesn't involve an instant break-up.
It occurs to Voice that airplane seats should include a heavy fireproof cloak with a valved pipe to outside air. In emergencies passengers could wrap this cloak around themselves and (when below 10,000 feet) if the pipe is working breathe through it.* Under ordinary operation the cloak would form part of the seat cushion. A simple modification of existing instructions could keep passengers protected until they can leave, if exiting is possible: add the following clause as bracketed. [If no one is in the isle beside you] start moving toward the exit.
optional: make the cloaks so they can be removed from the seats; include a dust or gas mask

NB If a fire-eater dies and is cremated, isn't that just excessively recursive?-- not_morrison_rm, Nov 13 2016 //valve piped to outside air //
Why not just integrate this with an escape hood? <link>-- scad mientist, Nov 14 2016 random, halfbakery
