2012 04 17 - 3157 - Washington DC - Space Shuttle Discovery
The Space Shuttle Discovery's final flight: a journey over DC on 17 April 2012, part of the retirement of the Shuttle program which entails DC receiving Discovery and our current Enterprise (a prototype which never flew into space) to be transferred to NYC in a couple months.
It was EPIC. I've never seen so many people on the rooftops of DC. I managed to fall as I sprinted from the east to west side of the Washington Monument, but did a perfect roll and came up kneeling & shooting photos... I felt very deft, other than the tripping in the first place.
Also, if NASA equipped that fighter pilot with a camera I will send them a paycheck.
