We see drums in the cargo hold. I know very little about aviation but it always impressed me that C-5s had drums of military specification hydraulic fluid in the cargo hold. They had to top off the hydraulic systems because of leaks. When I asked a (rightly-proud) C-5 crew member about the drums, he asked what I would expect from an airframe with miles of hydraulic lines.

General Electric TF39 high-bypass turbofan (TF-39-GE-1C) in its cowling. The TF39 was unique in having a "T-Stage" fan and "snubbered" first stage fan blades. It was also unique in that it only powered the Lockheed C-5 Galaxy (although it did provide the basis for the commercial GE CF6 high-bypass turbofan). Given the 1985 timeframe, it is almost certain that this engine was destined for a then-new production C-5B Galaxy, after C-5 production was restarted during the Reagan Administration.

The dark upper wing indicates that this airplane has gone through the C-5A wing modification program, but the black radome indicates that it's still equipped with the original Norden Multi Mode radar system. The replacement color weather radar system would likely have been installed during scheduled depot maintenance at Kelly AFB, at which time the rest of the airplane would have been painted in the three-color Euro 1 paint scheme.
