This caught my attention and I began observing the jets as they flew over spewing their trails. Some had regular trails that seemed to disperse within 10 mins or so disappearing from the tail of the trail forward. The others dispersed far more slowly and laterally, with no discernable "tail forward" diminshment.
This comprehensive study of an unexplained apparent dermopathy demonstrated no infectious cause and no evidence of an environmental link. There was no indication that it would be helpful to perform additional testing for infectious diseases as a potential cause. Future efforts should focus on helping patients reduce their symptoms through careful attention to treatment of co-existing medical, including psychiatric conditions, that might be contributing to their symptoms.
As I was watching one jet, it's trail suddenly stopped dead for about 5 - 8 seconds before bursting back to life. I that was a regular contrail, would that be a normal event.Would it not signify that the engines had been turned off briefly.From my relatively uninformed perspective it honestly looked like this jet was spraying something from tanks and one of the tanks ran out leaving a few seconds hangtime while the next tank was being opened.
Originally posted by waynos In truth there is only one sort of contrail.
Btw Morgellons has been shown it doesn't have any link enviromentally...

I stand by the video. I for one am old enough to remember when there were no chemtrails, only contrails. And I just can't get on board with revisionist memory.
So what about all the people who DO remember "chemtrails" (persistent contrails)?

The trails people see are generally exhaust contrails.

I think you are on the right track here. Jet airliners after they take off are almost exclusively flown by autopilot, at least until the descent stage. Anyone who is familiar with even simulators knows this. The break could have been caused by a manual adjustment to the autopilot setting or an automatic adjustment made by the autopilot itself which caused a temporary reduction to the throttle.

People who remember things that did not occur? Not sure. Guess they were on a different planet.
Last time I was in this little micro-argument it was said that the advances in jet engines were the cause. As someone who worked on an international airport for years, that bucket didn't hold any water either.
The breaks are caused by variations in atmospheric conditions. Contrails are just clouds made visible by the passing of the jet. A gap in a contrail is the same as a gap in the clouds. Gaps in couds can be very big, or very small. Sometimes, like clouds, the gaps can be periodic.
Maybe having worked at an airport isn't actually a qualification?

Yeah, I heard ya the first time.
And again I ask, why did we stop talking about the CDC?
So far all I have heard you say is"Nah!" and "Nuh uh". Quite convincing arguments when discussing an hour long video. And you still haven't clarified whether you even watched the video.
CONTRAILS typically form behind high-flying jets in a low-humidity environment. Cold, dry conditions -- exactly those found in the upper atmosphere -- are prerequisites to contrail formation. The humidity level of the upper atmosphere is LOW, which is the reason clouds form in the troposphere -- the lower portion of our atmosphere. Jet contrails, which occur at high altitudes (e.g., 40,000 feet) disappear quickly -- much like your breath on a cold winter day. They are simply made of water vapor. (Why do contrails disappear? They evaporate in the dryness, helped along by solar radiation.)
Now, boys and girls, CLOUDS need two elements in order to form -- particles and moisture. They require condensation nuclei (small particulates) for water vapor to adhere to. The size of these nuclei is about seven microns (picture a red blood cell). Clouds also need conditions of about 70% humidity before they amass at various levels of our troposphere. Clouds hang around for a long time, and come in basic varieties: cirrus (high altitude, feathery looking), cumulus (puffy and fat, with noticeable vertical dimension), and stratus (low-hanging ... those sheets of gray that create an overcast day).
The lesson: Clouds and contrails require opposite conditions to form! Don't forget this.
Today's news: We don't get to see a lot of natural clouds any more! ... So, what DO we see up there in the sky?
All over the world today, we are seeing "clouds" formed by "contrails" left by high-flying jet planes. For some reason, as of 1998 or so, the white lines behind jets stopped going away. (This would be like your breath staying in the air for hours on a winter day, forming big swaths of whiteness all around you as you walked.) For some reason, after 1998, there were SO MANY jets leaving white trails in the sky that lasted all day, making THE WHOLE SKY OVERCAST, that NASA decided we now had a phenomenon called "persistent jet contrails." But they cannot explain why they are persistent
