One thing to remember is that undoing a harness is impossible if you are disabled due to a severe head injury
Prune Fan#1,
You are right about folk forgetting the safety brief by the end of the flight but I can't imagine YOU making a smart-alecky comment, surely that's not something you're prone to, is it? (p.s. got my harness done up, helmet on - and a book down my trousers as a backup!)
