Yep, I'd agree with a few post's here!
Perhaps a little more thought should have gone into the placement of the bunks and exposure to ambeint noise...
I spent many an hour dossing down for combat kips in the military on the ground and in the air and it was always better with a little ambeint noise and a little warmth.
However, sudden noises, etc would soon snap even the most tired from a deep sleep.
I'm pretty sure most sleep study scientist's that work with in the NHS etc would confirm this, surely this is all part of human factors?????
