Hi Dan, great shots. But I do have one question. The Atlas V launch was
actually delayed from 8:29pm to 9:03pm that night, I believe there was an
aircraft detected in some restricted airspace (or something to this effect).
Did you actually take the shots at/after 9:03pm perhaps (as your photo details
state 8:29pm)? thx... dj
