Are you looking for China door factory?

Have you ever personally witnessed anything weird?

I’m a truck driver and yesterday I was at one of our customers warehouses. While there, I was standing not to far away from a loading dock door that lifted up all by itself. Now there’s no mechanism or anything attached to the door. It has to be opened manually. And I doubt the wind could’ve opened it up as the door has to be lifted open garage door style and is an extremely heavy steel door. And there was no one else anywhere near it when this happened.

Answer:

A few things. For instance, I had my telescope out one night to observe Jupiter’s moons, when suddenly a flashing white light flew low over where I was sitting. It moved very fast - fast enough to go from horizon to horizon in a matter of seconds, and made absolutely no noise.
