I saw last night's TRACE launch from my home near San Francisco. I could see a column of white smoke moving straight up from the horizon. At some point the smoke stopped and it was apparently travelling directly away from me (I was looking up the tail pipe). At 1x this looked like a large tailless comet. It then disappeared rather abruptly. The smoke began blowing in different directions even as I watched. All of this was while standing on a platform (no rails), leaning to one side (because of a distant tree) while my 4 year old shook my leg. Randy p.s. I saw no trace of Sunday's Iridium launch. Next time I'll try the roof.
