Aus 9/11 Wiki
"At 9:40 a.m. I was driving down Washington Boulevard (Route 27) along the side of the Pentagon when the aircraft crossed about 200 yards in front of me and impacted the side of the building. There was an enormous fireball, followed about two seconds later by debris raining down. The car moved about a foot to the right when the shock wave hit. I had what must have been an emergency oxygen bottle from the airplane go flying down across the front of my Explorer and then a second piece of jagged metal come down on the right side of the car."
I have given Bouchoux the benefit of the doubt and placed him at the point shown but he may very well have been further back. Needs confirmation but the '200 yards' (180m) distance ahead of him leans more towards NoC, SoC would have been rather 500 yards (460 m).
