The Attack
I had just reached the elevator in the 5th Wing of BMDO/Federal Office Building (FOB) #2 – call it approximately 9:36 AM. I was already trying to make some sense out of the World Trade Tower attacks having heard about them on the radio. The news was sketchy, but the fact that it was a terrorist attack was already known. I then realized that I was wearing sunglasses and needed to go back to Lot 3 to retrieve my clear lenses. Since it was by no means a short walk to my car, I was upset with myself for being so distracted. Approximately 10 steps out from between Wings 4 and 5, I was making a gentle right turn towards the security check-in building just above Wing 4 when I became aware of something unusual. I can’t remember exactly what I was thinking about at that moment, but I started to hear an increasingly loud rumbling behind me and to my left. As I turned to my left, I immediately realized the noise was bouncing off the 4-story structure that was Wing 5. One to two seconds later the airliner came into my field of view. By that time the noise was absolutely deafening. I instantly had a very bad feeling about this but things were happening very quickly. The aircraft was essentially right over the top of me and the outer portion of the FOB (flight path parallel the outer edge of the FOB). Everything was shaking and vibrating, including the ground. I estimate that the aircraft was no more than 100 feet above me (30 to 50 feet above the FOB) in a slight nose down attitude. The plane had a silver body with red and blue stripes down the fuselage. I believed at the time that it belonged to American Airlines, but I couldn’t be sure. It looked like a 737 and I so reported to authorities.
Within seconds the plane cleared the 8th Wing of BMDO and was heading directly towards the Pentagon. Engines were at a steady high-pitched whine, indicating to me that the throttles were steady and full. I estimated the aircraft speed at between 350 and 400 knots. The flight path appeared to be deliberate, smooth, and controlled. As the aircraft approached the Pentagon, I saw a minor flash (later found out that the aircraft had sheared off a portion of a highway light pole down on Hwy 110). As the aircraft flew ever lower I started to lose sight of the actual airframe as a row of trees to the Northeast of the FOB blocked my view. I could now only see the tail of the aircraft. I believe I saw the tail dip slightly to the right indicating a minor turn in that direction. The tail was barely visible when I saw the flash and subsequent fireball rise approximately 200 feet above the Pentagon. There was a large explosion noise and the low frequency sound echo that comes with this type of sound. Associated with that was the increase in air pressure, momentarily, like a small gust of wind. For those formerly in the military, it sounded like a 2000lb bomb going off roughly ½ mile in front of you. At once there was a huge cloud of black smoke that rose several hundred feet up. Elapsed time from hearing the initial noise to when I saw the impact flash was between 12 and 15 seconds.
