My pentagon floor plan theory finally has a second witness
Three years ago I posted here about the missing stairwell in the southeast corner of the Pentagon's 5th ring. Last Tuesday a retired Army cartographer from Arlington messaged me with a 1987 blueprint copy that shows the same gap. We compared measurements and his match my photos within 4 feet. Anyone else have a crossover source that backs up their original claim?
My 1981 USGS survey map finally matched my original photos down to the inch after I asked for the full legend sheet instead of just the top layer. Getting that second set of eyes made all the difference for me.
