If you are unable to imagine how taking your personal belongings may hinder a a successful evacuation of ALL passengers, take a look at the video,the link for which is posted in the Turkish Airlines incident,Kathmandu.
It is the Facebook video,with the still image of the evacuation,taken from outside.
Towards the end,there is the internal view,showing the potential chaos,if smoke or flames where to suddenly appear!
Can't seem to repost it myself...but as pilot and passenger,it gives me the willies to watch...
Comments about personal documents,I quite understand,but,after the bumping and sliding and graunching has finished,and you hear those words"unfasten your seatbelts,evacuate,evacuate"Are you really going to open the overhead bins,and extract them first!!!!!
Maybe,passport should always be with you...
Regarding the unusual use of the lifejacket!!!!Cold ears maybe!!!
