I was at my home in Kalispell, MTand I was going to the store when I noticed a very bright light light in the sky. I continued to watch the light thinking it may be a plane coming in to the Kalispell International Airport.As I observed the light for about 20 minutes I watched a plane coming in from the east headed towards the airport and the light did not move. I then saw another smaller aircraft fly by the light and the light did not move.I continued to watch the light for about an hour and I came in to get warm. I had told my brother about the light and I went back out to see if it was still there and the light had disappeared. We often have a number of sightings over the old military Airforce base outside of Lakeside,Montana. I believe this to be another ufo in this area.
