Re: Glossing a commercial turd
It's perfect for USA -> Europe. You go to bed on the plane like you would in a hotel room, but you wake up at destination, the idea behind London->Scotland sleeper trains of the past.
All that would be needed would be to streamline the airport processes at each end, the flight in the middle would vanish from your life and air travel would be less onerous.
I really don't need a high ceiling and a window if I'm asleep.
