It is not a myth. Normal contrails do dissipate quickly. That's why they made the terms "Persistent Contrail" and "Persistent Spreading Contrail".
It has been the common observation by a large group of intelligent and reliable people. Personal eyewitness accounts of people who have seen a change over the past 20 - 30 years of observing air traffic in a particular area. Contrails may have persisted in certain locations. But they rarely if ever persist in all the areas they are being seen today. I notice the change in my area.
The Battle for France and Saint-Exupery's Train of Frozen Stars
At the time Germany invaded France, French aviation pioneer and famed author Antoine Saint-Exupery was just short of his fortieth birthday, well past the age when men were considered fit for air combat duties. Given his age, his literary achievements, and health problems caused by earlier aircraft accidents, Saint-Exupery was not expected to volunteer for combat duty and could easily have honorably avoided it. However, he believed France was in grave danger and that all Frenchmen who could were obliged to come to her defense. (3)
True to his convictions, Saint-Exupery managed to secure an assignment flying reconnaissance planes, specifically, the Potez 63. Such an assignment was a serious challenge for a man of his age and physical condition due to the difficulties and discomforts associated with flying in the cold cockpits of high altitude aircraft. (4)
Saint-Exupery survived his combat missions against the Germans and escaped to the United States after France surrendered, settling into New York in January 1941. Here, he wrote about his wartime service and worked to build support for the war against Nazi Germany. After the United States captured North Africa, Saint-Exupery was allowed to sail aboard an American transport to Oran, Algeria. He then secured permission from French authorities to rejoin his old French reconnaissance unit, Group 2 of the 33d Reconnaissance Wing, and began flying combat missions after being retrained to fly the unit's aircraft. Shortly after he rejoined the 2/33, it was transferred to Colonel Elliott Roosevelt's 3d Photo Group, which flew the reconnaissance version of the P-38. By this time, Saint-Exupery was over forty-two years old, and regulations established thirty as the maximum age for pilots in Roosevelt's unit. Only through the intercession of a high-ranking French general with General Dwight Eisenhower's headquarters was this age requirement waived for Saint-Exupery. After being trained in the American P-38, he flew this aircraft on reconnaissance missions out of North Africa beginning in July 1943 and continuing until he was killed during a mission on July 31, 1944. (5)
In February 1942, while still living in New York, Saint-Exupery had published Flight to Arras, a memoir of his service against Nazi Germany in 1939 and 1940. Here, he described the challenges of his high altitude reconnaissance missions: the cold that could freeze the controls of his aircraft, finding and photographing enemy targets under fire, and the anxiety of knowing his plane was tailing a white streamer that pinpointed his position for enemy fighters and gunners. Regarding this last challenge, Saint-Exupery's wrote:
The German on the ground knows us by the pearly white scarf which every plane flying at high altitude trails behind like a bridal veil. The disturbance created by our meteoric flight crystallizes the watery vapor in the atmosphere. We unwind behind us a cirrus of icicles. If the atmospheric conditions are favorable to the formation of clouds, our wake will thicken bit by bit and become an evening cloud over the countryside.
The fighters are guided towards us by their radio, by the bursts on the ground, and by the ostentatious luxury of our white scarf ...
The fact is, I have absolutely no idea whether or not we are being pursued, and whether from the ground they can or cannot see us trailed by the collection of gossamer threads we sport.
Gossamer threads set me daydreaming again. An image comes into my mind which for the moment seems to me enchanting. "
Contrails may have persisted in certain locations. But they rarely if ever persist in all the areas they are being seen today. I notice the change in my area.
If you are attentive to contrail formation and duration, you will notice that they can rapidly dissipate or spread horizontally into an extensive thin cirrus layer. How long a contrail remains intact, depends on the humidity structure and winds of the upper troposphere. If the atmosphere is near saturation, the contrail may exist for sometime. On the other hand, if the atmosphere is dry then as the contrail mixes with the environment it dissipates. Contrails are a concern in climate studies as increased jet aircraft traffic may result in an increase in cloud cover. It has been estimated that in certain heavy air-traffic corridors, cloud cover has increased by as much as 20%. An increase in cloud amount changes the region's radiation balance.
Contrails can be found over most of the planet. Now that jet plane traffic, both civilian and military, can be at anyplace over the globe at anytime, contrails are becoming more and more common. This picture was taken by the NOAA-12 satellite as it passed over portions of Europe in 1995. It is very obvious from this color enhanced satellite image that the atmosphere was very conducive to the development of contrails on this date (5 April 1995) and that these contrails were long-lived enough to accumulate with many criss-cross patterns over the same heavily travelled portion of air space. Contrails have been recorded throughout the history of jet plane travel. Many reports exist from World War II of situations where the accumulations of contrails was so extensive that pilots were unable to keep visual contact with neighbor or enemy planes during combat. Contrails have been recorded from the Sahara Desert to the South Pole indicating that contrails are not constrained to only populated regions of the Earth.
If contrails persist for a long enough period of time, say on the order of an hour or more, they can spread out across the sky due to the prevailing winds at the level at which they formed. The two figures below show how contrails generated on this particular day spread out fairly quickly due to the stronger jet stream of air aloft. Persistence of contrails is neither an indication that they contain some kind of chemical, nor that it is some kind of spray. As a matter of fact, sailors have known for some time to look specifically at the patterns and persistence of jet contrails for weather forecasting. On days where the contrails disappear quickly or don't even form, they can expect continuing good weather, while on days where they persist, a change in the weather pattern may be expected.

It is not a myth. Normal contrails do dissipate quickly.

They do?
I guess this guy didn't know that as he was trucking along 55 minutes ahead of us at flightlevel 400.
So how big of a shadow did that leave on the ground, and shade how many people from sunlight.
Do you have anymore confessions/pictures of aiding in possibly breast cancer in women?
The group is willing post pictures of their crimes, all we have to do is save the links and their text of brags. As they fly over our heads and block sunshine.

Again blind statements with no links to back it up. BTW still waiting on those links I inquired about earlier and how about those cancer statistics that were caused by contrails?
Or have you not been able to find these things?
By all means take your time I know you have a lot of info to go through..

You can call it blind, I will just record your confessions of your crimes. Show me more pictures of your crimes.
You can mock me, call me names, what ever you want, while you show the world proof of your crimes.

Well I hate to burst your little bubble, but the state of Ga. has already beat you to the punch. Better luck next time.

I'm pretty sure that calling people criminal when they have not done anything illegal is immoral too...so thanks for adding evidence to support the suggestion.
So you are going on record, as none has ever had a cancer related to your industry. Pretty bold statement.

You still haven't provided us with any proof of cancer being caused by contrails, so that is a bold statement to say it has been caused by his industry.edit on 10-4-2012 by tsurfer2000h because: (no reason given)
