Keep in mind that the C-5 is a double deck aircraft. Cargo goes on the main deck and passengers go in the upper deck. The upper deck is similar to an airliner but without windows. In the event of decompression oxygen masks drop down just like in an airliner. Lights and alarms are similar as well. There are two big differences:
1. The passengers and loadmasters all face aft
2. There are two passenger compartments, one forward and one aft of the high mounted wing. There is no pass through between the compartments thru the wing.
The C model is the exception. The aft passenger compartment has been removed on the C model to provide a much taller cargo bay aft of the wing. This was done to accommodate large satellites and other space gear (official designation of C-5C is C-5A(SCM) which stands for Space Cargo Modified.). Both Cs were upgraded to the M configuration and are now C-5M(SCM).
