Like MrH said I remember the cabin crew being nice when they came around and smiling at me eventhough they knew that I was a prisoner. You can imagine what it was like being a 19 and after having spent 6 months in jail barely seeing any women!
I remember wondering what would happen if anything went wrong when they were doing the safety thing about putting on oxygen masks, getting to the door quickly, getting down a slide. Don't have a clue how somebody was meant to manage that with handcuffs on but maybe they would take them off?
I have to say everytime I fly now I think back on that flight which I'm sure is the strangest flight I'll ever have.
