Hi. I just built this tonight after watching Zero Dark 30 for the 4th time. Took me about 4 hours or so to build. Its pretty big, I don't know the exact dimensions, but it should be close to 1:1 scale. It's not perfect, but its I'd say 95% accurate to the real thing. As for references, I used a model made by Google in Google SketchUp 8, Google Earth, and a picture with some dimensions.
