Bright light in night sky over Gull Lake. ABDuring the evening, around 22 hours, My girlfriend and I where having a romanic moment, by lying on the beach and looking at the stars. A bright pin light appeared in the sky at at 11 oclock.At first I thought it must be the MIR station conducting a light reflection test that I heard about, But the light was not moving, just shining towards us. We where talking about the light, giving it a number of possibilies, when the light dim, and suddently steak across the night sky and out of sight.I am a retired military person and have seen a number of military aircraft in flight, none could ever match the speed this craft had. No sonic boom was heard.((NUFORC Note: Witness indicates that date is approximate. PD))
