Following the AF 340 and the successful (if a bit slow?) evacuation, just HOW do we get the pax to understand that it is IMPORTANT to get off toute-suite and that their handbaggage should stay where it is - or they may have no hands with which to hold it?

Did they think they were on stand? Let's take a picture of the happy evacuation.
This assumes, of course, that the reports are correct.
Is it time that the airlines'
PR darlings allowed PAs that actually frighten the pax into listening and learning rather than pussy-footing around with 'should the cabin air supply fail' etc? How's about 'if a bomb blows a big hole in the fuselage at 41,000ft, make sure......'?
Only joking, naturally.........
BUT - it obviously is not getting through. We are even told that it was a SOP to REBRIEF the evacuation on the way into destination. Any ideas?
