Hand luggage in emergency evacuation
In other threads, concern has been expressed at the unwillingness of passengers to disembark without their hand luggage, thus potentially, endangering others.
As a thought, modern cars have a central locking facility: could this not be applied to aircraft overhead lockers?
It would still leave some passengers with hand luggage in their possession, but if operated as soon as the emergency is known, would the sheer unavailability of access not encourage the majority of passengers to accept defeat and just get off the aircraft?
Am I being naive or is it technically too difficult?
