I saw the same thing about a week ago. By the time I noticed them I was only able to count 9 all running in the same perfect line, perfectly spaced apart, on a E/SE heading and moving at a pretty good clip. Saw several other "space truckers" out there jumping from one spot to another. Appeared like the whistle blower vids of TR3B. Saw them for several nights always appearing in the same spot of due S sky and often well after the time all the sats have disappeared from view due to the sun being too far beyond the horizon for reflection. Saw 3 craft the night of the line of crafts that were moving, at least, 4-5 times faster than any sat which usually average around 14K mph, most times. That would mean these things were moving around 50K+ mph, give or take, depending on altitude. Truly space truckin', they were.
