Chemtrails

[Smersh999]

A number of web sites, including www.rense.com have been reporting that aircraft have been flying through the skies of the US and elsewhere spraying out chemicals (as opposed to the normal "vapour trails" created when flying at high altitude.)

In the "Black Helicopters" thread I mentioned chemtrails and Prezhousin made a post in which he claimed to have seen these chemtrails being made: pub2.ezboard.com/farmaged...D=52.topic (http://pub2.ezboard.com/farmageddononlineforumfrm7.showMessage?topicID=52. topic)

Has anyone else seen any of these chemtrails, or has an explanation for them?

[VegasRonin]

Here in Las Vegas, especially in the summer time, chem trails are pretty common. Even the fabled "X" shaped chem trails. I have no idea what the purpose is behind the trails but they are a rather new occurrence. I was a witness to a rather strange Ariel phenomenon about 8 months ago, and I wasn't alone in seeing this. One particular day there were more chemtrails in the sky than usual. This military jet, F-16 I think, was flying a straight path through them. There was what appeared to be a "Black Laser" type of light shooting from the front of the jet and clearing the way ahead of the plane. The "Black Laser" seemed to clear the chem trails ahead of the jet by a distance of 3 to 5 miles. The person I was with when this was happening is also a Military Vet, and Nellis Air Force Base isn't very far from us. We just figured they, the Air Force, was testing some new feature for their jets. Area 51 is also very close to our area but who knows. :cool:

[lotrfan553455]

I have been getting rashes off and on ever since I have came to the USA so I'll watch for chemtrails when I get one.:smokin:

[mickydoolittle]

Perhaps the chem trails are causing certain members to post cryptic messages...:roller:

oh, and lotr...go see a dr...a dr can give you some ointment to rub on that rash...:lol:

[MoonlapseV]

this is a VERY interesting website devoted to chemtrails and chemplanes. I was reading about the incident in Ohio and decided to look up chemtrails and i found this.

In June of 2004 the U.S. Postal Service released a new set of Cloudscape postage stamps. These images are startling and thought provoking, as more than half of the cloudscape classifications depicted are visually identical to their man-made knockoffs -- the chemtrail cloud formations.

For those of us who are aware of this ongoing covert operation, and who still retain the ability to think and see for ourselves, we must ask: Why the heck would our government issue these stamp designs?

To answer this question we need to consider the necessity of plausible deniability that surrounds the Chemtrail spraying programs. This program would never have gotten off the ground if it had been limited by environmental law and regulatory processes. So it was conceived as a black-ops project to be carried out in secrecy. And it will remain secret, even if it's proponents have to brainwash every person on Earth to accomplish it.

These stamp designs are intended to help condition people into thinking that the unusual cloud formations being sprayed above their heads are natural phenomena. Indeed, chemtrail formations do closely resemble their natural counterparts.

Other chemtrail public relation projects include: The constant presence of chemtrails in TV commercials, print media, and feature movies. These are just a few of the ways that they can keep the lid on this volatile topic, in order to continue global atmospheric geoengineering,

Stay tuned, as next year they will be working diligently to convince the sheeple of the United States of Amnesia that the sky has always been white, and that blue skies only exist in our dreams.

How do you tell the difference between normal plane trails and these Chemtrails?

[RavenWhitefang]

How do you tell the difference between normal plane trails and these Chemtrails?

A normal trail will disappear after a few minutes. chemtrails spread out and become wide bands of clouds that cover large areas.

If you go HERE (http://shop.usps.com/cgi-bin/vsbv/postal_store_non_ssl/html/clouds.html) you will see the other 11 stamps in the series that were not shown above. None of which look to me (including the 4 above) like anything other than what they are, clouds. The last one in the series is a pretty cool twister picture. If indeed chemtrails look like natural formations and people are being conditioned to see cloud formations (that are really chemtrails) that they would normally only see if they ,um, looked up in the sky then what would be the purpose of using these pictures? Boy am I confused.

Do I question the existence of chemtrails? Nope! I believe the government has and will continue to test new technology without informing us.

Do I question a theory that the USPS is part of a coverup conspiracy on this issue based on the evidence above? Yes. If you honestly think about how much if any attention you pay to the average postage stamp, then consider that those four are only 4 in a series of 15 and god only knows what the odds are of 1 of those 4 appearing on the vast majority of stamped letters (over 280 million a year) and so on and so forth ad nauseam..........Please give more proof that the USPS is part of this.

and evidence for this statement

Chemtrails - A New Look At
A Mystery In The Skies
By Colin Bennett
11-14-4
http://www.rense.com/1.imagesD/CHEM3.gif

The so-called "chemtrails" that are seen almost everywhere in the skies of the world are an incredible phenomenon of our time, if only because like UFO sightings, the broad span of social, political, and intellectual life of major nations largely ignores such things utterly. Even those with imagination (artists, playwrights, novelists, poets) ignore such anomalistic things as UFOs and chemtrails, even though they offer images, symbols, metaphors, intrigue, mysterious technology, and much more besides! This changing of the skies of the world full previously of traditional pantomime clouds to a sky scored by lines of whitish-grey streaks is totally ignored by major news, media, and communication outlets. This is strange again given that the effects are quite spectacular and beautiful when lit by the evening sun. The trails spread out at different rates, they come from different angles, and the aircraft that create them can be seen streaking across the sky, often several at once, and at extremely high speeds.
The word "chemtrails" is used here for lack of a better word, but it is unlikely that what we see spreading out across the sky are chemicals of some sort. Such an amount of chemicals would surely have the most immediate and obvious effect on both our minds and environment. We would be please to hear from environmental group who have more specialized knowledge about any kind of chemical/environmental approach.
Over the past year, the Combat Diaries team have conducted a special investigation of chemtrails over Britain. With the help of specialists (some ex Royal Air Force), we conducted a 16 hour period of observation by web, telephone, and amateur radio of the skies over America and Central Europe, from first light to last light, taking into account time differences. The results were quite disturbing. It was obvious that simultaneous operation by large numbers of quite visible aircraft were being mounted over continental areas on both sides of the Atlantic. Through contacts, we managed also to get reports on this selected same day from the civilian staff of merchant and cruise ships crossing the Atlantic. They reported that sky trails were visible in whilst sailing in mid Atlantic.
Thus we concluded that chemtrails represent a continuous operation of incredible magnitude. The aircraft involved show remarkably similar characteristic and performance, though their profile we have yet to find in any book of aircraft recognition. Roughly, they resemble in shape and size the Boeing 757 (the type that crashed into the Pentagon on 9/11), but carried no markings. This is remarkable in itself, because technically it is illegal. Measured by range theodolite and ex-service hand-held rangefinders, they were doing approximately the same speed at the same height. The speed was steady, quite precisely maintained, being 1200 *1400 mph. This is somewhat high for an outmoded passenger aircraft type, meant for inland short/medium range commuter flights at a top speed of 450 mph!
These things are wonders in themselves, but it is the sheer number of these pseudo 757-type aircraft that is beyond belief. On this chosen sample day, our reporters in France, Germany and Holland, Spain, Italy and Israel alone reported at noon the sky trails of no less that 234 almost identical aircraft at between 40-50,00 feet Since this hourly rate continued during the day it represented some 2340 sorties over ten hours. Worldwide, multiplying the quite reasonable factor of 10, we have 23,400 sorties per day by planes of a non-military non-supersonic configuration, travelling at speeds equivalent to the combat speed of F16 or Typhoon Euro-fighter.
By comparison, NATO figures for annual full-scale exercises amount to something like 300 (jet supersonic) combat sorties at full stretch for the same time period, involving some no more than 150 aircraft. Again, the absence of reported noise is strange. Even a single Tornado on afterburner over central London would shake the population up considerably.
Since our observers at military and civilian airfields reported no such activity by any such aircraft, we have here a modern mystery in our skies visible to all on a clear day. National airspace regulations don't appear to be a problem at all with any country as far as these infringements are concerned.
This vast number of aircraft appear to have no detectable bases, they have no apparent air-refuelling needs, they do not carry drop tanks, and the routes appear to stretch across the sky from all compass points, often crossing one another on a pretty random basis. They appear also to have no detectible manufacturers, support base, or refuelling facilities. And they don't appear to land or take off! Again, since no air force in the world (not even the United States Air Force) has any supersonic transport aircraft, the presence of many hundreds of supersonic transport aircraft is rather strange!
The cost such of such visible operations on a worldwide basis by the approximately the same type of powerful aircraft must be stupendous. The maintenance, fuelling, and repair facilities of such a great number of high-performance aircraft can only be imagined. The training schemes and accommodation of the personnel appear not to exist! Since no such numbers of this aircraft type are on manufacturer's lists, and the number that have been manufactured are all busy on conventional routes flying conventional passengers and cargo, we have here a true mystery of our time.
Where are they from, and what are they doing on their seemingly purposeless routes across the sky?
Investigations are continuing. We are trying, by various means to monitor their VHF, but they do not appear to have any measurable frequency signature and neither do they appear to make any physical noise. This again is amazing because the represent a very great number of aircraft that are entering and leaving (an indeed manoeuvring) inside national airspace at will, with no recognition signals, and no visible identification. Since they are supersonic, they are over the visible horizon in seconds (the comparatively lazy motion of a 400-mph 747 Jumbo may be compared to them). Where these many aircraft all break into Mach 1 is another mystery.
We have discovered something else that multiplies these astonishments. Using (passive) night scope infrared amplifiers, we found that the operations did not cease after nightfall!
This means that roughly speaking we can possibly multiply the scale of operations by a factor of two, bringing us into absurd realms as regards cost, maintenance, and purpose.
Our collective "not-seeing" is unusual if only because chemtrails are much more visible and more frequent than UFO visitations. We are forced to consider the idea that levels of conscious acceptance and recognition within a culture have often nothing to do with how much "evidence" is available. All anomalistic structures have this common peculiarity. Somehow, like a bioelectric switch, as a society we turn most anomalies "off" as far as social cognition is concerned. This is a most common effect. The phenomenon may be large or small, fantastic or mundane, it makes no difference. We cannot see the kitchen matchbox in front of us, say, because we are have been diverted into thinking about something else. We don't have enough RAM to hold all our files open at the same time!
From a Fortean point of view, the phenomenon of chemtrails might enable us to construct a new and healthier definition of what we mean by "skepticism." We might see skepticism not a revealing of mundane truth, so much as an automated control mechanism by means of which maintain a kind of wonder-management rather than differentiate fact from fiction. This was Charles Fort's original view of the function of skepticism. It puts "doubt" in a new dynamic context rather than it being seen as a depressing semi-automated denial of all that is wondrous and magical in the world.
Meantime, we are starting the long, hard road of corresponding with the appropriate civil and military authorities about chemtrails.
We can hear both Franz Kafka and Charles Fort laughing from their graves!
Colin Bennett was born in Robin Hood's Sherwood Forest, within arrow-shot of the Sheriff of Nottingham's castle. He left school after studying science and mathematics, became a professional musician, then a mercenary soldier before winning a scholarship to read English at Balliol College, University of Oxford.
After leaving Oxford, he had several plays performed on the professional stage in London including the Royal Court Theatre before retraining as an electronics engineer to cure what he calls "a bad dose of left-liberal decadence." After his reconstruction, he then ran his own electronics consultancy and printing firm. He has had two novels published, and now lives within a spear-throw of Portobello Road, London, and hopes he has done with reconstructions. He is frequently consulted on security, conspiracies, and computer hacking. He now heads a team who spend all their time running the Combat Diaries web site at http://www.combat-diaries.co.uk
He is the author of Looking for Orthon (Paraview Press) a biography of George Adamski. His following book, on the life work, and ideas of Charles Fort, was Politics of the Imagination (Head Press). This won the Anomalist Award for Best Biography, 2002.

CONTRAILS - CHEMTRAILS
http://www.crystalinks.com/chemtrails.html

http://www.crystalinks.com/contrails316.gif
Chemtrails are spread by fleets of jet aircraft in elaborate cross-hatched patterns are sparking speculation and making people sick across the United States. Condensation trails, called contrails, are generated at altitudes high enough for water droplets to freeze in a matter of seconds and not quickly evaporate - typically where the temperatures are below -38 degrees Celcius.

Chemtrails can form through the addition of water vapor to the air from the jet engine exhaust. Even tiny nuclei released in the exhaust fumes may be sufficient to generate ice crystals, and hence, condensation trails.

The strange spray patterns are being reported repeatedly over towns in Tennessee, Connecticut, New Hampshire, New York, Nevada, Idaho, Mississippi, Montana, Oklahoma, Washington state and California.

Cobwebbing stuff coming down from the zigzagging jets flying all day long, line after line, back-and-forth, like furrows in a farm field.

Immune system symptoms include swollen hands and legs, night fever and shortness of breath.

Hey Brian,
I see you already have some other chemtrail postings from New Year's Day in Pennsylvania. Obviously it was exceptionally bad over most of PA and I hate to have to trump those other guys but apparently I'm at "ground zero". (Not that I'm the least bit glad of that fact) Looking at these it's not hard to imagine why everyone has respiratory problems in this area. To all the skeptics just keep telling yourself this is "completely normal". Without further ado I'd like to present the Mother Lode.

... some think there is something sinister going on above our heads in broad daylight
and go as far as to descibe certain patters as " chemtrails" can you please...

http://www.weatherwise.org/qr/qry.chemtrail.html

If you are interested in chemtrails you may find this site interesting.
The essay verifies something that I suspected when I first started hearing about chemtrails.

[prezhorusin04]

Nice link Sword. I do however think that these chemtrails are causing illnesses that many do not even know about. They are being poisoned by chemtrails and most people have not even yet noticed an increased amount of chemtrail spraying!!

Think about it..How would you kill an "insect" infestation? You'd gas them. Though they do it now in such a manner that it's a slow and creeping death..

Personally, i think that Chemtrails are for weather control purposes, though i firmly believe that they are making SOME people sick..

A lot of those pictures are just normal clouds...

As for anything else, well, the conditions in the sky are different than on earth, and depending on temperature, they will stay visible for a while. If the government wanted to poison people, an easier way would be water supply.

I think so too. It may be in affect and we wouldn't be able to notice. Just imagine this poison having long term results, say an estimate of 10 years down the road if it were released today or perhaps a few years back.

No, maybe one pic could have been normal cloud. The rest were made by aircraft. I see these things everyday. They are not normal by any stretch of the imagination. Perhaps the reason is not poising, perhaps it is an effort to stop global warming, or weather control, or both. Barium and Aluminum are highly reflective and conductive and they have been found in these trails.

These things have only been showing up since around 1999. If they were just contrails as some people like to claim. What changed in 1999 that made them persistent and spreading? Why on certain days when they are happening, are not all the aircraft making them? Some days I have seen 3-4 persistent chemtrails along side 5-6 quickly disappearing ones. What makes those 3-4 SO different that they not just stick around longer; they NEVER dissipate and eventually form fake clouds.

A far as poisoning the water, that very well may have been happening for sometime, under the guise of fluoride... There have been no studies on the long term safety of these chemical we drink everyday, and they very well could be causing cancer. Hey but at least our teeth are shinny!


Stewy, this stuff effects you and your family if you have any. Wake up dude.

[lotrfan55345]

I have come to percive that chemtrailing is weather control and/or some experiment.... that makes people sick.

They chemtrailed 'Nam for weather control purposes... which is a public and released document.

i don't know about anyone else, but i've ignored stewey.
i am of the belief, that
1) he has imbibed too much Flouride,
2) smoked too much crack, dope, and/or fiberglass,
or 3) is a government paid debunker.

he's silenced a few posters by posting buzz words about classified information and NDAs. that or people were reluctant to post due to other interests, i don't know, i don't care. all i know is, this guy is hopeless and non-perceptive. i didn't think people could be so dense, i was wrong.

Agreed.

However even these paid shrills, will have to face the music the same as the rest of us. He breathes the same air as you and I. He will face the same police state as you and I. Maybe eventually some will begin to stand up for truth, hopefully it won't be too late.

Put your tin foil hat away...

You see, in geography class we learned that the air is different higher up, and the effects of exhaust from planes stay there as "clouds". If the government wanted to poison you, they would use shit that is invisible and undetectable. There is no police state coming, so settle down spaz.

[prezhorusin04]

Stew, we're all in the same boat friend, whether you want to admit it or not..

You don't know a police state isn't coming, just as much as i don't know that it absolutely is.

The fact of the matter is, there are many mechanizations in place that could very easily bring a police state into motion.

As for chemtrails, i don't really care what anybody else has to say on this matter. I know for 1000% factual proof that there is a VAST increase in chemtrail emissions over the past decade, all i have to do is look outside on any given day..

They are going in every direction. Even strait up and down, which are the most suspicous ones of all..

And many people HAVE had their health effected as a result of chemtrail emissions. They just don't know it yet..

This stuff is NOT staying in the air. There are "cobweb" like substances being found on lawns and trees all across America, in specific relation to areas that are being sprayed with Chem-trails..

I'll be back and post more on this later... :2thumbs:

Ok first of all you wouldn't learn about air currents and tempatures in geography class. LOL!

Secondly. Contrails never stayed for hours and hours till 1998. Funny that was shortly after a report was writen deatailing a way to curb global warmiing by blocking 1% of the sun light.

Also I never said they were trying to posion any one on purpose. I made the assertion that it was for some type of weather modification. The posioning could just be a fringe benift.

You are kinda a bad shrill dude. Don't they have a class for you guys? Maybe just working overtime on a bunch of boards. People kinda getting out of hand huh?

[stewey]

Ok first of all you wouldn't learn about air currents and tempatures in geography class. LOL!



Umm yeah you would... Meteorology is a subdepartment of geography at my university and many others. It considered a lab science, which you must take at least 1 of (sometimes more depending on your degree, mine requires 4).

For example: http://www.indiana.edu/~geog109/ (not my school, but i did a quick google search)


Let me explain the science behind "chemtrails"

First of all, warm air can hold more moisture than cold air can.

In the part of the atmosphere where these jets fly, it is real cold. The jets output water vapor in their smoke. Because the air is so cold up there, the air cannot hold as much moisture, so the water vapor from the smoke condensates. Water vapor needs an item to condensate on, to "attach" itself to. The other items from the jet's smoke (smoke in itself, for example) is what the water vapor attaches itself to.

Logical argument: if the government wanted to chemtrail us, theyd use an invisible chemical.
