not sure of exact time or day but it was during the meteor shower in august 2007 , I never miss those events, at first I thought it was three satellites moving at the exact same speed, moving exactly the same space apart, but then realized that was imposible. I know nothing flies south to north in the northern skies, out in the middle of nowhere.It made no sound and made no chemtrail either. this is in southcentral alaska 50 miles west of Glennallen. This event happened in late july or early august. I noticed also at least 10 meteors over six to eight hours late in the evening and morning, it was a slow meteor sighting night. I noticed most is that it was dark out but clear and it was moving , direcltly overhead perfect triangle with light on each corner.watched it till I could not see it any more to the north. the next couple weeks after things seemed kind of strange, cant explain though in words.
