Fantastic idea by Core77: how do the crew rest compartments look like? You know, these hidden places where the attendants and pilot alike rest during long flights (don't tell me you didn't know those existed!!).
I actually had the chance to visit the rest area on an Emirates A380 (that same visit I briefly recounted two weeks ago) and it really does look like the above. It sits at the back of the lower deck, in the middle, as seen below (the big blank rectangle):
Where do the pilots go though? Next time you're on a A380, go on then lower level at the very front. Opposite the main staircase that goes upstairs (which is reserved to First Class passengers on Emirates for instance) is a small three-step staircase leading to the cockpit (unlike the 747, the access is actually from the lower deck!). One of the doors there opens to the below reality:
(Good try though, Core77, that bed you've chosen looks awesome!)
Those are the most "visible" rest areas however. The rest areas on the newer A350 are hidden above the overhead compartments (at the back for the crew, at the front for the pilots).
Some B777 also have the rest area above the economy class, at the rear. They often come with small bunk beds, power sockets, reading lights, even crew pajamas on some airlines.
Check Chris McGinnis's report on the "secret staircase":
Being above is a relatively novel idea though. Most commercial aircrafts have had those rest areas hidden underneath the passengers. You can take a look at this great photo thread on Airliners.net to see some cool examples. The B747 has those hidden under the tail. You also have to go down on a A340.
You're basically in the hold, but have much better leg room than most of the passengers!
Head to Core77 for a few more images.
