Strange bright light pops out of cloud, then back in, over Toronto Canada.Thursday July 4/02, I had just finished playing hockey and was standing in the driveway of my neighbour who had done the driving. It was approx 11:10pm. We were chatting for a few minutes, when all of a sudden a very bright white light appeared in the sky across the street. It was to the east of us and about 1/2 way up in the sky. It looked like a large bright headlight. I could see no structure behind the light.In the space of between 5 and 10 seconds the light moved out of a cloud, then did a sharp left and upward turn and went back into the cloud. I was waiting for the light to reappear but it didn't. We waited several minutes. No light. I said to my neighbour pointing "What is that". He saw the same light.For some reason I put this out of mind. I knew it was unusual, but I couldn't account for what I had seen. I never thought about it again, even while at Mufon. It just seemed not too significant.If it was an airplane, there were no running lights on it.Then on July 15 I received an email from someone who lives the other side of Toronto from me. I live in the west end, and the woman lives in the east end. The woman said she, her husband and their son saw a brightly lit object to the west of them, on Thurs July 4 at approx 10:30pm. She wanted to know if anyone else saw something strange that night.I'm trying to contact someone at Pearson International Airport, but so far haven't got through to the control tower. There's a good chance they won't confirm my sighting. I also want to see if I can find out how low the clouds were that night, because this thing just popped below the ceiling, and then retreated right back in. My guess would be 5000 ft.
