On a cloudy night in Minnesota I was on my back patio looking up towards the west for any stars and a light came into view that I assumed was a star until my eyes adjusted. I noticed it was in the shape of a bird soaring and it was moving slowly towards the east. It was moving about the speed of a plane and after about 3 seconds it disappeared behind a cloud.I just tried to shrug it off until a few seconds later I saw another farther down the sky and another flying very closely by it. One disapeared as if into thin air and the other disapeared passed the clouds. As the clouds moved I saw a few more come into view,a few at the same time and a few going faster before disapearing.I kept looking up for about 30 minutes; I didn't see anything else but I saw about 7-10 of these flying lighted objects within 5 minutes.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
