Like i would be totally ok to have 50cm heigh bunks like in an uboat, but most ppl would probably get quite anxious in such a coffin. If you are not thin you cannot rotate in such a bunk or even put your hand on your stomach, or even fit into it.
I prefer sleeper trains to intercity buses, even when not needing to sleep, exactly for that: you can travel with dignity. You can sit upright, stand up, or lay down, which you can't do on an intercity bus.
I’d sleep on floor if stewards let me
I've flown a 15 hour flight at least a dozen times in economy.
Trust me when I say there is no dignity after 14 hours of trying to get a little sleep with your mouth wide open, snoring loudly, drool coming out and your head lolling onto the person next to you.
When I think of that 15 hour flight the very last word in my mind is dignity.
It’s an interesting mental exercise, but honestly I think this madness needs stop. If flying is not profitable enough, then we need to plaster the country in passenger rail.
I like the idea of plastering the US with passenger rail, but I think that'll be very expensive to install and run.
These solutions are targeted at 15+ hour flights - I don't think anyone's building high-speed rail from London to Sydney anytime soon.
100%, that is absolute nightmare fuel
