I didn't plan on seeing it and assumed that I would miss it since it was making its low flying rounds in Washington, DC. However, since McLean is right in the pathway to Dulles Airport (it's final destination before being housed in the Air and Space Museum), it was a fortuitous surprise!
Here is a video from one of my co-workers...aren't the cheers great? Can you see the fighter jet (I think that's what it was?) flying alongside of it?
Did you get to see the space shuttle today? If so, did you plan to see it or were you surprised like I was?
