There should be no ambiguity about any personal effects in that situation, nothing is vital and can be replaced, passport is a bit of paper, mobile phone, there are millions of them, start telling people to keep them about their person and they will start transferring it when they should be getting off a burning plane, as realistically several hours with your passport, wallet etc in your pocket isn't comfortable.
Get off the plane, that is all there is to it, worst comes to the worst you get to do a Tom hanks in the airport for a few days and have a tale to tell when you get home.
I get so frustrated with other passengers with their massive carry on luggage, just check it ffs and perhaps not get up and faff about with it every fifteen minutes ? the maximum bag size should be half the size is it now, just deal with the baggage reclaim.
this does have echoes of the Manchester disaster, obviously no two incidents are exactly the same but 30 years on this resulted in a ruined plane and a few sprains and bruises by the sound of it, not 55 funerals and life changing injuries, I saw that pall of smoke when doing my paper round that morning in 85, its nice to think that this result is partly down to the lessons learnt from that incident, and some good has come from it 30 years hence, that and the performance of the industry, crew and emergency services, if not all the passengers....
