Dupre...seems reasonable...but some of the launches have more glass (much larger windows).
Dr Red....also make sense and is often the second thing people say when I ask this question (the first being fuel load) - but I doubt that even NASA meteorologists can predict weather forecasts down to six minutes for some eight sites around the globe (is it eight - or six?, something like that).
Quid...I'll go with that too...but you say yourself "for a given radius of orbit there is only one speed"....so change the radius with a burn and change the speed to catch the satellite...no?
