Before I give the link, a word of warning.
Ensure that your mouth and hands are empty and that you have a clear route to the bathroom or a handy bucket. Put anything you might be able to use to poke out your own eyes well out of reach. Check that your tray is in the stowed position, that the ashtrays are closed and your seat back is in the upright position. (I remember the days when the 'no smoking' lights used to go out, you know).

And now, the same image, after ironing.
Modern laundry technology is truly amazing.
