A few months ago, I was recording this unusual event in the sky. I've never seen anything like it before. There were planes and jets flying above the cloud layer. It was that strange cloud layer that seems to accumulate like a canopy over the sky. It actually makes the clouds really shiny and bright. There was this line that seemed to trail across the sky. In the past, you would never see a shadow on the clouds above you. I though maybe it was a laser or something. In order to create such a distinct shadow in the sky, on the clouds, wouldn't there need to be a large amount of metals above us?
