"we went out on the wing but there wasn’t a chute there"
It's unbelievable how stupid people are.
Are you saying they are stupid for using the wing exit or for expecting some way down to the ground from there?
I've listened to many safety briefings but can't recall any that said not to use the wing exit (look for your nearest) or explaining how to get down?
Only five days ago people broke legs jumping off the wing..
