If you want to get items/bags out of the overhead lockers during an emergency evacuations may l suggest the following.
1. Always sit in a window seat, so you will not get in the way.
2. Exit the a/c after everyone else.
Remember if someone goes out the door with a bag and rips the slide, no one is going out that exit after you have.
One other issue l have noticed over the years, more and more emergency evacuations are taking place for problems like hot brakes and engine failures. Years ago the Captain would use his experience and common sense and wait for the emergency services to attend the incident.
I have read reports of air-conditioning ducts rupture while the a/c is on stand, sending clouds of dust into the cabin and the crew blowing the slides.
Sometimes l wonder if in an emergency evacuation, l might sit tight and wait for everyone to get out before deciding if l want to get out or not.
