The northward trail of the booster may have been an optical illusion. It may have actually tumbled off at about 90 deg from the trajectory (more possible) and looked like a northward trend from Salome Field.

Note that was an evening launch and the exhaust trail was illuminated. I too was stumped on the sudden northward turn. The only plausible hypothesis I could think of was the spent booster, still venting, tumbling with any residual thrust pushing it northward. Though I doubt that as I would think any residual thrust wouldn't; have been strong enough to overcome it southward momentum. I would expect this launch to be visible along the coastal areas and inland a bit, but I truly doubt anyone at Salome field will see anything. I've gotten up at 2:00 AM one too many times to try again. Like Jim, I'll be again the inside of my eyelids :) Rick K7TEJ ---- Dan Heim <dan@xxxxxxxxxxxxx> wrote: > I think he's talking about this Atlas launch (Sep 20, 2010) around 9 pm. > Put together a time lapse.
