I fly out of there on Palm Sunday in April. Its been a while because we live much closer to Dulles. I do remember when I was younger we would do a circuit on our bikes around the Mall, the Potomac, and across the various bridges to the park right by the end of the runway. https://en.wikipedia.org/wiki/Gravelly_Point. Great airplane watching location. Horrible tragedy. I have seen some numbers on local tv of victims.
