Would playing a 'professionally produced' video of the chaos that ensued on the EK evacuation (with the associated chatter which drowns out the CC instructions) - followed by a 'public information message' in several languages outlining the hazard associated with collecting and carrying 'carry-on' luggage be a good idea - to be screened during the final approach of the aircraft - or would that induce panic among the passenger who would then assume that the aircraft was going to crash?
