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:
I was driving to work in helena in front of murdocks.Object looked like a hot air balloon at first.As i drove under i slowed down directly under the object.Street lights reflected off the bottom of a grey shiny yet dull metal. i stopped the car and got out. looking directly over my head. no sound or lights. it looked to be a massive metal boomerang that had seams to it where big parts came together like a hit air ballon seams. due to the objects size and way the light reflected off it i cant correctly judge the size of this object. the lights reflection looked like small spots on it as it took up most of the open sky. it was coming from the east going slowly to the west. then as it got out of under the street lights it disappeared as there was no light on the side streets to aluminate it. there was no sound. no lights. no windows. it was directly over head for a full minute. this object gave no indication if it was occupied or by whom or what. after a full minute of it flying over my head as i was out of my car in the middle of the street i followed it south in my car where it cleared the street lights ans disappeared. stunned is how i felt. who would believe me? i was alone with no proof of what happened.
