I've been on the C-5. The general passenger compartment looks okay (between tail break and front break). The flight crew area is in good shape.
Where do the loadmaster(s) usually sit? Would a relief pilot be in that area of the front break?
The forward upper deck (flight deck) seats a cockpit crew of six, a relief crew of seven, and eight dignitaries or couriers; it also has two bunk rooms with three beds in each. This area is just in front of the wing.
