You posted that list of threads on the freakin previous page.
You don't have to cram it down the throat of every single poster that disagrees with you.

I have completed a canadian commercial pilots course and This is my area where I did my training I know the vector airways here.On a hot summer day in the middle of a big high presure system the atmoshere is pretty calm and no where near cold enough to create a vapor trail.

It is entirely correct that airplanes at or below 18,000 feet are very unlikely to form contrails...the air just isn't conducive to that, at those low altitudes.
These planes made four passes over about three hours the trails did not dissipitate they spread and slowly drifted toward the valley and would spread out and look like high cirrus cloud they would last up to seven or eight hours.
The most common form of high-level clouds are thin and often wispy cirrus clouds. Typically found at heights greater than 20,000 feet (6,000 meters), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus generally occur in fair weather and point in the direction of air movement at their elevation.
Sorry, a cloud formed by aircraft exhaust trail, is not a cirrus cloud.
"The ONLY reason this "chemtrail craze" has developed, worldwide, is due to the ignorance, of the general public at large, of the science of meteorology!!"

...wonder if we could coin a new term --- "cirro-cumulus"?
Cirrocumulus clouds are high-altitude clouds that usually occur at an altitude of 5 km to 12 km. Like other cumulus clouds, cirrocumulus clouds signify convection. Unlike other cirrus clouds, cirrocumulus include a small amount of liquid water droplets, although these are in a supercooled state. Ice crystals are the predominant component, and typically, the ice crystals cause the supercooled water drops in the cloud to rapidly freeze, transforming the cirrocumulus into cirrostratus.

Contrails
The white streaks you see coming off high-flying jet airplanes are called contrails, which is short for condensation trail. Contrails are clouds that formed when water vapor condenses and freezes around small particles that exist in aircraft exhaust. The water vapor comes from the air around the plane and the exhaust of the aircraft.
