On the last plane I was, the door was 17kg and instructions said to pick it up, turn sideways, then throw away. I prefer strong men to do it when my life depends on it.

I googled if it was possible. It harder mid flight, but take offs or landing its much easier. I would rather we accept the fact this risk exists and take the necessary precaution of putting someone at the door that can more handle the situation than pretend it doesn't exist.

To me it seems the biggest dangers about exit doors are not accidents. But someone who snaps and wants to open the exit door during take off/landing where the outside air pressure is low enough to more easily open the door. In this kind of situation a strong man doesn't hurt.

unless the strong man is the one that wants to open the door.

i think i've heard of someone trying to open a door mid flight once though, so unless i'm poorly informed, let's not give the TSA ideas around mental health screenings before flights.

You mean when the inside air pressure is low enough. Aircraft doors fit like a plug, held in by air pressure in the cabin. If you look when they are opened they all move inward first. This is why they can't be opened mid-flight.

At the point where they can be opened, the pressure differential is going to be so low that nothing bad is going to happen, other than maybe someone's bag in the exit row being blown out by the wind. Plus everyone should be strapped in at that point.

This happened just last year IIRC in Korea. Nothing was in serious danger (except maybe some travel schedules). A comment already described the mechanism and why that’s not really a thing to worry about.
