Two days ago I watched a large cargo (chemplane?) and a smaller plane flying right near it. Could the smaller plane be monitoring the aerosol content? See Gallery page. I’ve seen those stunning photos captured by pilots flying behind planes leaving massive contrail ropes suspended in the sky for miles. They have a few on this Canadian site.

AirshipAl has gone deeper into the rabbit hole with the shadow trails. He’s comparing his footage of the recently captured shadow trail (left) to a freeze frame taken from a local TV weather time-lapse image (right).

This is amazing, notice the consistent angle of shadow trail with other contrails. We were reminded of the planet’s ley lines. We also realize we need better equipment to capture the detail of these highly sophisticated operations. Nice work Airship!
