When you're on a long-haul flight to Asia, you know how important it is to get some sleep.

You'll probably be all right if you're in first class. Flying economy? Good luck.

But what if you're a member of the flight crew? Turns out that on Boeing's 777 and 787 airliners there is a secret stairway that leads to a tiny set of windowless bedrooms for flight attendants and pilots. After all, they also need sleep on journeys than can take 18 hours or more.

Passengers aren't allowed up there, and few people know they even exist. Here is what those upstairs bedrooms look like, via YouTube videos from Chris McGinniss at Travelskills.com and Chris Jepson and the Flickr account of Martin Deutsch.
