Thanks, Richard.

I was amazed that the furthest end of the plume appeared to be so far in 
front of the two craft. I think some of this had to be due to parallax. 
Could solar wind also be a factor?

Great shot! But I am curious. The shuttle was moving at a pretty good clip,
so how does the plume move so far away from the trajectory so fast? It looks
roughly like the plume was moving at about half the shuttle's speed. That's
an awful fast displacement for a vapor dump. Anyone have any ideas?

I got up early this morning to catch the pair over Tucson at 3:19 am local.
Was pleasantly surprised to see Endeavor(?) performing some type of dump. At

least I think it was the shuttle because it was the dimmer of the two. The
plume from this event was pretty neat.
