For those interested, below are some links to a virtual tour of the C-17.
These are for T-1, the C-17 test aircraft, which was essentially a prototype. It was not built to production configuration so it is missing many items/systems (like the lavatory and crew rest bunks) and includes many items not in the production aircraft (like an upper deck test engineer station and an escape chute to enable the test engineers and test pilots to rapidly escape out the aircraft from the upper deck through the bottom of the aircraft while in flight.)
I'll be happy to field any questions.
