The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
We were driving from great falls to helena when i noticed a flashing red light like on a tower , but this was in the middle of the north and south bound lanes of the highway. when we got closer a spot light beam turned on and shown straight down. a few seconds later there was a second spotlight as one light flew onto the south bound part of the highway that we were on. the second light stayed in the same spot. then the light on the south side proceeded to get in the right lane that we were driving in and flew straight over us, the light lit up the inside of the car like it was day time. after a few feet of flying over us it then did a 90 degree turned and went into the hills that were right by the road.
