"F/C" in this case stands for Fuel Cell.
The rectangle in Discovery's side, clearly visible above the left hand corner of the flag in the above right image, is one of "....18 vents and outlets in the fuselage skin." These vent ports allow "....unpressurized areas to depressurize during ascent and repressurize during descent and landing." The ports are especially visible along the length of the cargo bay.
The body flap extends out below the main engines. "With its aerodynamic and thermal seals, the body flap provides the Shuttle pitch trim control and thermally shields the main engines during reentry."
Space Shuttle Discovery safely tucked away in the nation's attic.
