if it is so common let's see if we can come up with some similar videos. -
There are tons of them on Youtube.
This one is a prime example.

So, I have some questions about this video. I thought that contrails disappear right away unless the water vapor has turned into ice crystals, which usually happens at only about -40 degrees or colder, so why is this happening in this video at ground level? Shouldn't the exhaust gases be superheated?
I agree that persistent contrails may form at -40 degrees or colder, but how can that be happening in this video at ground level with a superheated exhaust?
How will we know if we are onto something with this video? It will disappear from youtube as most incriminating chemtrail videos do.
Somebody's high school science class forgot to teach them about the ideal gas laws relating pressure to temperature, and about Bernoulli's Theorum. What you see in the video is a "chemtrail" only in the fevered imagination of those who value their pet theories over scientific fundamentals. What you see in the video is an atmospheric environment of saturated air (100% relative humidity.) Fluid dynamics tells us that if you accelerate a gas, you reduce its pressure (Bernoulli.) Thats why an airplane flies. If you reduce the pressure of a gas, you reduce its temperature. That's why a fire extinguisher shoots "snow" when used. You know - P1V1T1=P2V2T2. And when you cool saturated air, condensation happens. That's what causes fog, and rain, and other wet stuff. The ability of air to carry water vapor is directly proportional to the temperature. The camber of an aircraft wing, or control surface, or nacelle or any other curved part accelerates the air, reducing its pressure, thereby cooling it and thereby phase changing water from vapor to liquid. What the OP ludicrously calls a "chemtrail system" is atmsospheric physics, and the pilot can't turn it off. If "chemmies" would learn a little high school science, they wouldn't be laughed at nearly as much.

Because if you read most chemtrail sites they aren't talking about cloud seeding. They are taking about contrails not being contrails.

so what happens to the air after the aircraft has left the area? of course it should return to the same state as the surrounding air right? so persistent contrails are what then?

Its funny you provide people (schills) with proof wether good or bad and gets only a response of insults.. hmmm
