ZOMG!!! I found the island where the reptilian space aliens have their secret underground base and send out the mind control rays!

Condensation trails do that too.
When a jet tears through the sky the air going over the wings experiences a rapid pressure change. When temperature, pressure, and humidity are right this causes humidity to condense into water droplets, which you can see. If the air is fairly dry then these droplets will evaporate and the contrail win disappear. If the air is humid and it wants to form a cloud, but was just waiting for something to nucleate around, then the contrail will not evaporate and will instead spread and help nucleate more cloud formation. If the air is cold then you can get tiny ice crystals.
What people attribute to "chemtrails" is within the range of normal atmospheric behavior.
They can also be particulates in exhaust gases. But let's not over complicate things.
Trump knows… about water ballast tanks used to simulate the weight of passengers and cargo to test how an aircraft behaves when the center of gravity is moved around.
He's in on it, I tell ya'.
Those are interesting. Pressure/temperature/humidity are not constant throughout the air. If I had to take a wild stab at what was causing that I'd say the jet is downwind of a mountain ridge and Lee Waves coming off of it (or something related) were creating a pattern of varying conditions.

It's been investigated to the point that I want to junk when I see another melted aluminum wheel.
First YT comment on that video…(pic related)
Most races were easily predictable. If there were only 6 toss-ups, for example, then they only have to have 64 videos.
