Getting there: we flew from Dover AFB, crossing the North Atlantic, to ROTA Naval Air Station, on the south coast, just west of Gibraltar.

We flew aboard a C5A, a huge transport. The passenger area is in the top of the plane, above the cargo area — roughly delineated by the red line.

Looking "back" in the passenger area, with seating for ~90 people. Note the fenced off area and the knotted rope. The fence is around a hole in the floor that leads down to the cargo deck. It keeps people from falling in.

Another knotted rope leading to a door. An airman, serving as a steward, confirmed my supposition that the knotted rope was to aid in case of emergency egress from the plane.
