Chemtrails - clouds of death - DivX documentaire.

quote:

Eventually, all clouds and contrails will dissipate, but the length of time they endure is related to the atmospheric conditions as well as the strength of the winds. If the contrail is formed when the local atmosphere is dry, it may dissipate rapidly. But if the atmosphere is near saturation, it will exist for a long period of time, perhaps spreading or mixing with naturally-formed clouds until it is unrecognizable as a contrail.

quote:

It is for this latter reason that many climatologists have become concerned about the increase in air travel over recent decades. It has been estimated that cloud cover may increase by up to 20% in some heavily-traveled areas due to man-made contrails. This increase could have a significant effect on the climate in those regions since clouds block solar radiation. Designers of modern stealth aircraft must also be concerned about contrails since they can easily give away a plane's location to an observant enemy. While methods have been developed to inject (usually toxic) chemicals into a vehicle's exhaust to eliminate contrails, it's usually far more preferable to simply increase or decrease altitude until the atmospheric conditions no longer support their formation.

Nee, dat is geen onzin. Daar heeft ze gewoon gelijk in. Ik zeg het niet alleen, tienduizenden mensen constateren wereldwijd hetzelfde, namelijk dit enorm grote verschil met vroeger, zo een 10 jaar geleden. Dat is een vaststaand feit waar eigenlijk weinig discussie over mogelijk is. Oftewel, als jij zegt dat contrails vroeger exact hetzelfde gedrag lieten zien als vandaag, dan noem ik jou een leugenaar.

quote:

Formed at 12,000 and the weather caught us. Couldn't climb fast enough to keep out of it. So we took off on our own to avoid any planes in the clouds. Six of our wing men went home when they became separated from us. We left England on our own and headed across France for Strassbourg. The contrails were dense, persistent - really hard to even see our own squadron. Our Air Leader really got worried about us being by ourselves. Jack and I had to argue like the devil before he saw the light on the bomb run. He wanted to bomb in group formation with just anyone. We wanted to take our 7 plane squadron in by ourselves. On account of Whitt is really an expert on PFF (couldn't bomb Micro-H - too far from the beacons). Then - on the bomb run the bombsight froze up, due to lack of precautions by our visiting bombardier, and Whitt dropped the bombs, aimed PFF at the center of Mannheim.

quote:

Yes, we certainly did. Contrails were so thick that they became clouds. We often said that we created weather over Europe. They would persist for many hours, maybe days. We flew a different route coming back than going in partly to avoid the contrail clouds that we created. There are some pictures of contrails on my web site - none of these are shown to be very heavy but there were time when we were near the end of the bomber stream and the contrails were so dense that it was no dfferent than flying in clouds. A thousand or more
planes (4000 internal combustion engines) can make a lot of contrail at 25000 feet or more.

quote:

As you've assumed, the bomber crews as well as our fighter escort saw
contrails about every day even though an effort was made to avoid them. As
was often said, they represented large fingers pointing to the bombers.
Obviously of assistance to the enemy fighters who could spot us at a
considerable distance.

The nature of the contrails was such that they required certain atmospheric conditions to form. Thus, they were principally affected by altitude. At the pre-mission briefings, they typically advised us of the altitude that the formation of contrails could be expected with an effort made to avoid that particular altitude. More often than not though, we did in fact make contrails indicating that their information was faulty or that flying at that altitude couldn't be avoided. We in B-24s typically bombed from about 22,000 feet while the B-17s, which could fly higher, bombed from around 27,000, particularly at tough targets where higher was better in an effort to avoid the flak as much as possible.

My recollection is that the contrails persisted for some time. While I don't recall timing them, I would guess that they could be seen for fifteen minutes or more. At times, Germany appeared to be almost covered by contrails as far as you could see. Essentially creating a cloud layer which could possibly persist for hours I suppose. The bombers' in more or less straight lines, the fighters', usually above us, more random as they criss crossed or circled. A common sight was the escorts dropping their tanks and heading off after the bad guys.

Die foto's van WWII bewijzen helemaal niets. Je kan adhv deze foto's echt niet zien hoe lang ze blijven bestaan, verser kan zowat niet. Nee, laat maar foto's van die periode zien met hetzelfde GEDRAG (dus uitwaaieren tot zeeeeeeer brede wolken) waarbij we echt duidelijk kunnen zien dat het er al lange tijd hangt. Gaat je niet lukken.

Hoeveel commerciele vluchten met straalmotoren denk je dat er in die tijd waren
Misschien 2 per dag ofzo.
En denk je dat iedereen toen een camera ofzo had
je hebt wel over 60 jaar geleden he!


ohja, als reactie op je foto met een ronde 'chemtrail' (die overigens ook enorm vers is)

Nou dan graag vergelijkbare foto's vanaf de jaren 50 tot en met jaren 80 graag. Dank u wel.

In practice, the speed of dissipation of a contrail can be from a few seconds to hours.

quote:

The goal of this research was to determine if there was a type of trail that was inconsistent with normal contrails, especially with regard to increased persistence. What was found is that highly persistent trails that last for many hours were seen above Houston, TX on a majority (60%) of observable days during the data collection period. However during this time period none of the 46 Flight Explorer confirmed contrails observed persisted for over 30 minutes and most contrails were under 30 seconds of persistence. Additionally it was discovered that the jets that were responsible for leaving highly persistent trails that last for hours did not ever appear on Flight Explorer and were documented for 8 separate instances, including one instance with two jets in formation. These unidentifiable jets were found to produce a contrail that was consistent with confirmed contrails during the periods when they weren't leaving highly persistent trails. Highly persistent trails are often seen in the form of isolated relatively short strips, as well as large areas of cirrus aviaticus clouds, but on rare occasions have been seen in totally unique grid and wheel formations.

It is hoped that others will endeavor to repeat these observations and publish their results. By repeating the basic observations for persistence length and whether the flight appears on Flight Explorer, it will be seen whether or not a trend emerges confirming the existence of a unique category of trail. Atmospheric differences due to higher moisture and colder temperatures in different locations will produce greater maximum persistence observed for identifiable traffic. For those in locations with greatest contrailing potential, the task of collecting data on highly persistent trails from unidentifiable flights will be hardest.

In this research I have gone to great lengths to measure and characterize my observations as accurately as possible in order to provide the clearest representation possible given the resources available.

Dat contrails er toen waren geloof ik wel. Maar niet dat ze toen hetzelfde gedrag vertoonden als tegenwoordig. Ook doordat het gaat om heel ander soort toestellen. En doordat de patenten heel oud zijn, waardoor het mij bovendien niets zou verwonderen dat in vroegere oorlogsperiodes ook chemtrails zijn gebruikt. Dus graag, als het gaat lukken, vergelijkbare foto's als die ik eerder postte vanaf jaren 50 t/m 80.

The above photograph is courtesy of The Churchill Society. The contrails of fighters overhead St.Paul's Cathedral in London during the height of the Battle of Britain added a reassuring sign that the pilots of Fighter Command were hard at work. The lattice of condensation trails marked the paths of RAF Spitfires and Luftwaffe Bf109s engaged in mortal combat during the long summer of 1940 at altitudes in excess of 30,000 feet.

Wereld oorlog 2 dus

According to Tarver, there might be anywhere from 500 to 1,000 B-17Gs strung out for one mission.

" With the contrails of 1,000 planes ahead of you," he said, "visibility gets real mushy.

" One day, we were flying through solid contrails and couldn't see a thing. I looked sideways and saw another squadron coming at us, at the very same altitude.

Still, he does discuss a number of weaknesses that MiGs had.

* they were not supersonic, even when diving...
* the T-shaped tail obscured your view and often was fatal when exiting the cockpit....
* the double-wall canopy would often fog up....
* there was no rear view mirror...

Authors comment. Rear view mirror?? Fighter pilots use rear view mirrors? Do they use turn signals too?
* poor fuel economy....
* long and visible contrails from Soviet jet fuel..
* lousy tires.....

Uiteindelijk, denk ik, dat het neerkomt op besef. Ik denk eerlijk waar, dat sommige mensen gewoon niet in staat zijn om chemtrails te beseffen, of nog erger, ze niet willen beseffen.
