I'm going to wander in as an observer - before wandering out.
Every time there is one of these evacuations there are comments about dumb passengers not listening to the briefing, and taking stuff that they should not.
If these really are issues perhaps the industry should change the way that it works, as the safety briefing clearly is not working in its current form.
As it is everyone got out, with few injuries, so perhaps its not such a problem.
