Feb. 2009 Approximately, 10 P M Our security camera recorded a bright light along the west side of our property moving approximately/from south to north, and appears to beam down perfectly vertical. .The light seen on from the corners of the building/by camera is 200watts and lights that area for security.The bright light of unknown origin from the sky is TREMENDOUSLY brighter than security,considering it beamed down through trees the entire distance it lit up that drive area.There is also a building electrical line running through the tree limbs from south/southeast to north/northwest above the drive.The trees are approximately 30 feet tall and NONE of the limbs , or the electric line were seen in light beam.There is an interstate within 1 mile south that you can hear traffic flow if the road is busy, it was not at that time. There are numerous dogs in the local area and they normally bark loudly at ANY movement. They did not.This area is down in a valley ,two city blocks east there is a hill that rises 200feet.This area is within 5-10 miles of the path of the triangular UFO spotted by Numerous local Police and reported on the local News and on T V on a show that was titled UFO over Illinois in another ,year previous to this situation.I am familiar with planes, helicopter, balloon/hot air, ultra light air craft. There was NO SOUND from any of these. The camera sound is on loud at all times.You could hear people talking from 20 feet away from camera using a normal speaking voice,if they were speaking.I have no idea what makes a beam of light SO BRIGHT and straight down, moving at that slow of speed.Anyone that has seen the attached video are uncertain also. All my life I have had interest in the unknown,and have seen UFOs in other areas of the country many years ago.
