I challenge you to find a single example of any cloud behavior or cloud formation that was not due to some sort of moisture in the air...
It's a UFO mining the cloud. They do that, not sure what they are mining though. When you see the cloud look like it's being sucked in, that's the UFO's work there. Amazing find!
