And they never do. Have had many friends who have evacuated aircraft and they always say, "You would not believe the sh!t they come running with, thinking they're going to go down a slide carrying a 50 pound roll aboard..." One of my friends was grabbing it out of their hands and chucking it to the side.
I remember in recurrent, hearing about a crash in Ca where two passengers were fighting to get out of the plane first, at the overing exit, I think, and passengers died from smoke inhalation because they couldn’t exit.
