About carry-ons
Would it be an option (cost, additionnal weight, wiring, power supply, etc.) to have the overhead bins automatically locked in case of an evac?
The harder part would be to get the pax used to the idea that there is no point in trying to recover personnal belongings in an emergency, I guess.
To weight pro and contra, beside common sense, is there any facts, test or study about how much of an impairment, i.e. danger, it is when pax struggle for their stuff in the midst of an evac ?
