[on the morning of September 11, 2001] I flew out of Dulles Airport about 7:30 that morning - actually about 50 minutes before American Airlines 77 flew out of Dulles. I often wonder whether or not ... did my path cross with any of the terrorists in the terminal or any of the 64 people that were on that aircraft and were killed at the Pentagon later that morning? But I, you don't know, but I'll always wonder that.
