Earlier Building 4200 Engine Display

Marshall Space Flight Center's headquarters building, Building 4200, had an engine display as early as June, 2004. The next-oldest Google Earth imagery is dated 2002, when the engines were not yet present.

These engines were removed by the late 2007/early 2008 timeframe, during which time they were refurbished and prepared for the new engine display (although I am uncertain as to whether the SSME shown here is the same one as was later installed in front of 4200).
