Approximately 5am tuesday morning i witnessed 15 to 20 spacecraft (i think because they appeared at satellite height) moving from nw to sse at less than meteorite speed, but more than satellite speed. at first noticed three moving in said direction, then as i looked directly above me five to ten more were racing to catch up with the lead craft. i then observed that two or three craft were joining from either side of the flight path. more were following trying to catch up with what appeared to be a formation. as all of them past, there were what appeared to be stragglers trying to catch up with the main formation. this all happened within what seemed to be about five to eight minutes. then all i saw was stars regular satellites and commercial aircraft.
