Blockhouse 5/6

One of the rooms in the Cold War Gallery is called "Blockhouse 5/6," containing Mercury and Gemini artifacts, including a window from LC 5/6, a Redstone A-7 rocket engine, some smaller Mercury-Atlas 1 debris, a Project Mercury chimp couch, an Atlas LR-89 (booster) rocket engine, and an Atlas missile start tank.

The wall around the entrance to the gallery is made up to look like concrete, and even the ceiling tiles have been dyed grey to evoke the image of being inside of a concrete bunker. There's a "periscope" containing a video display on which one can watch Mercury launch videos.

The blockhouse also provides access to Gemini-Titan launch pit.
