I've been sneaking \naway from work to try to catch the late morning/lunch time passes and \nthen staying up till 2:00 am catching the night pass. Now, I'm stuck at \nwork and can only leave for an hour so have to miss the first pass \ncompletely and probably the first objects of the second pass. Hopefully \nthis weekend will be better without work in the way.\n\nSorry if that seemed like a rant an 73, \nJonathan Wagner, KE5FSG\n\n\n\n\[email protected] wrote:\n> If I may offer a suggestion:\n>\n> I believe everything came off the rocket in the same orbit plane or \n> very nearly.
