Just seen the video of the evacuation. Why were "items" being despatched out of the windows in between crew members? Surely getting out of a burning airplane and surviving is far more important than saving your flightbag/leather jacket/personal effects. Maybe it was the catering? Sorry, bit of an underhand comment. Glad those seven on board got out ok and wish them a speedy recovery.
It looked to me to be a personal decision, so you will have to ask the egressors on what basis they made those choices.
I hestitate to second guess those individual decisions today.
