I was hanging out on the bank of the Potomac, so when the rocket came up over the hills, it was reflected in the water. I didn't get any photos (I would have had to be on my kayak to avoid the tree branches in the frame), but it was still amazing to see. My one friend kept saying "there it is" and I kept explaining that no, rockets don't blink, and those are all planes flying into or out of BWI. When we finally saw it, there was no mistaking it for a plane.
I wonder if some of the people on the plane saw it - I recall flying on the 4th of July once, and seeing some fireworks shows as we descended.
Apparently it was visible all the way up to Massachusetts. Did you see it? Did anyone get photos?
