2 or 3 orange lights moved from west to east over Great Falls, MT, very fast, silent, March 14/15, 2010Somewhere between 2100 and 2130hrs, my wife and I were sitting in our hot tub when my wife caught light movement to the southwest of our property. She called for me to stand up so that I could view with her as two orange objects streaked across the southern sky from west to east. Travel from horizon to horizon took less than 5 seconds and, even though the travel pattern was basically straight, it appeared as if they moved closer and then farther from each other as they traveled. The following night (March 15, 2010), at approximately the same time, the same event occurred but this time there were three of them and they were more directly overhead, again, moving from west to east. This time the maneuvering between the three objects was much more obvious as the distance between them closed and then opened several times. Basically, though, the trajectory was straight and very fast. There was no noise on either occasion.
