Yes.
But I can totally see me automatically taking the backpack then pausing because I’m not supposed to take it then pausing because what if it’s faster to just go even with the backpack, while there’s noise and confusion and probably passengers screaming in general and at me. So ending up with the backpack.
I have no idea what I’d do if our plane crashed but I do know that everytime I get up during a flight I have to lift my backpack.
Yes I’d probably be dead.
