Re: The problem with this idea
"Hell, if that gives me an unterrupted night's sleep on a US-Europe flight I'm in!"
Sleep, or possibly a nightmare from which you can never awake.
The idea reminds me of a Steven King short story called The Jaunt. Somebody invented an instant teleportation device but you have to be unconscious before you can go through it, otherwise you experience eternity and go mad. I'm sure Ryanair are keenly examining how to monetize this service if it ever becomes a reality.
