I grew up with parents in the air force. I was out on the airfield frequently as a kid. I saw what contrails look like in multiple environments, and we went to watch planes take off for fun as a free past time activity.

Contrails don't make the perfect grid line clouds I saw in the sky in Colorado about 8 years back. With multiple planes flying in close coordination leaving streaks across the sky for hours.

Yea chemtrails are real. People have set coffee cans out in their yards when they see them form, and then tested the dust that settled afterwards. Multiple heavy metals, things that don't just naturally float around in the air, were found.

It's fucked man.
