‘Chemtrails’ and Other Aviation Conspiracy Theories

Chemtrails or contrails in SitgesOliver Smith, writing in the unlikeliest section of Britain’s Telegraph newspaper (Travel), pooh-poohs the concept of chemtrails and, seemingly not satisfied with rubbishing that conspiracy theory, tries some other aviation-related theories out for size:

The seemingly random appearance of “contrails”, as these lines of condensation are commonly called, is considered by a small but vocal online minority to be evidence of government conspiracy. The clouds are, according to some, in fact “chemtrails” – chemical or biological agents sprayed at high altitude for any number of top secret reasons.

So persistent is the chemtrail theory that US government agencies regularly receive calls from irate citizens demanding an explanation. Pernilla Hagberg, the leader of Sweden’s Green Party, even raised the issue in parliament. The trails which arouse the most suspicion are those that remain visible for a long time, dispersing into cirrus-like cloud formations, or those from multiple aircraft which form a persistent noughts-and-crosses-style grid over a large area.

So what possible reason would the world’s governments have for secretly jettisoning vast quantities of chemicals into the stratosphere?

The conspiracy theory took root in the Nineties, with the publication of a US Air Force research paper about weather modification. The ability to change the weather isn’t mere pie-in-the-sky. Cloud seeding – where particles such as silver oxide are sprayed onto clouds to increase precipitation – is commonly used by drought-prone countries, and was part of the Chinese government’s efforts to reduce pollution ahead of the Beijing Olympics in 2008. Other proponents of the “chemtrails” theory say it is an attempt to control global warming, while some cite far more sinister goals, such as population control and military weapons testing.

Governments and scientific institutions have of course dismissed the theories, and claim those vapour trails which persist for longer than usual, or disperse to cover a wide area, are just normal contrails. The variety of contrails seen in the sky is due to atmospheric conditions and altitude, they say, while grid-like contrails are merely a result of the large number of planes that travel along the same well-worn flight lanes.

Patrick Smith, a pilot, also dismisses the theory in his book about air travel, Cockpit Confidential. “Contrails are formed when humid jet exhaust condenses into ice crystals in the cold, dry, upper-level air ­ it’s not unlike the fog that results when you exhale on a cold day,” he says. “Contrails are clouds, you could say. Water vapor, strange as it might sound, is a byproduct of the combustion within jet engines, which is where the humidity comes from. Whether a contrail forms is contingent on altitude and the ambient atmospheric makeup – mainly temperature and something known as vapour pressure.”…

    CorpGov Lied: Chem-Sprayed Civilians in the 1960’s

    Think the chemtrail crowd is wrong? New research being unveiled today
    says that indeed, the Army sprayed unknowing civilian populations with
    dangerous chemicals from 1945 to 1970. The research paper is publicly
    available and here’s the summary:



  2. So, why was the technology to spray chemicals from jets at high altitude ever invented? There are about 20 patents for this technology. The German air force has admitted to spraying aluminum.

    “So what possible reason would the world’s governments have for secretly jettisoning vast quantities of chemicals into the stratosphere?”
    It’s not cloud seeding. It’s surveillance and monitoring. And yeah, no shit there are such things are persistent contrails. But that just demonstrates that intentional chemtrailing is sometimes visible and sometimes not– it does not explain the grid patterns and the subsequent hazing that happens on what seems to be a fairly regular schedule but visible only during certain conditions.


    • Spend an afternoon in a hammock and you’ll understand the grid pattern. Planes follow regular flight paths, and the whole sky moves in unison. The result: A grit pattern.

      Under certain conditions it spreads out, other times it’s invisible, other times it’s disappears quickly because … there are different atmospheric conditions.

      It’s easy to establish a means, an opportunity, and a pattern of criminal activity. But I’ve never seen a motive that makes sense on a global scale, as most claim, and I’ve never seen any evidence that it’s actually happening. It’s possible, and is probably happening on a small scale, so I look from time to time, and I just don’t see any credible evidence.

      And then the people supporting it talk about this grid stuff and I just tune out. Watch the sky for more than an hour and see how the grids develop.

      • so you don’t see any possible motive in the ptb affecting weather patterns daily with unannounced ‘geoengineeering aerosol science’ to produce a result they can then blame on a population via ‘climate change’…which can then be utilized as leverage against a population to control every aspect of their lives? …there’s no control to be gained?

        also… so there’s absolutely no money to be made in weather derivatives by knowingly affecting the weather in specified areas?

        lastly,if documented weather modification like cloud seeding, is being done on a daily basis,then is it also factored into or even mentioned as a possible contributing factor to consider in climate change studies/reports?

  4. I’m very skeptical of Chemtrails. It’s seems like an inefficient, stupid way to poison people if that were one’s goal.

    But then I see photos like this one taken in Britain. The pattern is like a farmer plowing a field.

  5. Contrails dissipate. Chemtrails do not. If they are normal flight path contrails, why do they appear in large number on some days, and not at all on others? Why are they often concentrated in different areas of the sky? It’s clearly not from commercial air travel. The only question is, what are they? The only thing that’s clear is that those in authority are not telling the truth about it.

    • Silent Waft | Sep 24, 2013 at 3:03 pm |

      Different atmospheric conditions on different days, temperature fluctuations and different altitudes , etc

      • Understood, but how do you explain a contrail suddenly becoming twice as wide, over a few km, then resuming it’s normal size (In this case I saw it happening right before my eyes). And then that the “normal” size trails dissipated in minutes while the others (the wide trail) remained for most of the day. Oh and did I mentioned that I saw one single jet creating many persistent trails, turning around many times to create parallel lines. This jet was evidently not following a formal fly path and was flying at a really high altitude.

        • kowalityjesus | Sep 27, 2013 at 8:45 pm |

          I’ve seen it happen with a plane that was absolutely clearly a jetliner. The atmosphere does not seperate itself into horizontal layers. Conditions from updrafts and downdrafts will effect the state that jet exhaust manifests in.

    • mindofsound | Sep 24, 2013 at 6:56 pm |

      As mentioned in the article, (and as an educated guess might surmise,) the longevity and intensity of contrails is affected by altitude and atmospheric conditions like temperature, barometric pressure, humidity, wind, and air quality.

  6. I often see them spraying early in the morning (more
    frequently during the summer) in Ottawa… You can clearly see the
    “regular” contrail coming from the jet, then all of a sudden the jet
    trail becomes 3 times as wide as the regular trail, creates a big line, then
    the jet resumes with the regular contrail while turning around, then creates a
    larger trail again. They do this for a while. I saw one jet creating about 10 of
    those thick lines one time and they are flying at a much higher altitude than
    commercial or passenger planes. The regular trail from the jet disappears within
    minutes, while those larger trails remain in the sky all day. So don’t give me
    that “it’s the atmospheric condition” crap. I do understand how
    atmospheric condition can affect contrail behavior, but what I am seeing is clearly
    intentional spraying of some sort. For what purpose… I wish I knew

    • Rhoid Rager | Sep 24, 2013 at 6:40 pm |

      Where in Ottawa are you observing this? I used to live in Vanier and I remember seeing thick lines that lingered in the sky.

      There’s so much power vested in controlling Ottawa. The whole city is poisonous. I’m glad I moved away.

      • This one event I was about 8 km from center town, at a bus stop. I work on the Quebec side, right across the river from the Parliament. The jet was flying really high so the trail should have been visible over a radius of several kilometers (I could see them just as well from my work when I arrived there, which is about 10 km from my home). Anyway, I a skeptic at heart, but after seeing this happening in front of my own eyes, I could not deny that something was being sprayed. Here’s a shot I took that morning when I arrived at work. (All the trails were created by the same aircraft flying at really high altitude) These lasted all day.

        • Rhoid Rager | Sep 25, 2013 at 8:57 am |

          Shit man. Those trails look familiar to be honest. Many a times I’ve seen trails like those sitting on my neighbours backyard porch in Vanier. We’d smoke weed and look up at the sky. When you smoke weed, you’re observant of things you’d sooner ignore when you’re sober. I miss weed now that I’m here in Japan. But those trails look rather normal for Ottawa from my memory. High cirrus clouds in a straight line.

          Known plenty of people that work across the river. Sounds like you work at the museum. That place gives me the creeps. Propaganda central for Ottawa. I like how they tuck the Native displays in the dark basement, so you have to wander around down there incidentally after you watched a show on the stage flanked by stolen totem poles. lol. Canada is fucked up. In some senses worse than the US, because Canada doesn’t even acknowledge what the governments have done to the people who lived there before the whites came. lol. It’s all coming back to them in the end.

          • Well had I not seen them being made while I was watching, I would not have given it any thoughts. But I could see a tiny tiny jet releasing trails on an off for about half an hour. After that day I started checking the sky every day, but only witnessed them being made one time after that. Haven’t seen any of those trails in months now…
            Don’t work at the museum though…way worse, guess what, it involves a certain Mr. Harper…I have been feeling almost ashamed to be Canadian since that jerk took office. So sad to see how Canada’s democracy is eroding with that oil sand’s dictator as PM. And I also completely agree with you on the aboriginal issues, seems like they are never going to catch a break. Just last year our dear PM decided to go see a Panda at the zoo rather than acknowledge the Idle no more protest going on on the hill. Priorities eh!

  7. it’s amazing to me that science itself can literally propose geoengineering methods now,that stipulate & describe the same exact method of dispersal using aerosols via planes..and oblivious fuckers still want to make like aerosols (chemtrails) & weather manipulation are an absurd ‘conspiracy theory’. no,it’s a reality.

    the gov. has been gradually introducing it to the public,packaged/sold as a ‘last ditch’ effort/solution to stave off climate change with the legitimized term of ‘geoengineering’.

    it’s social engineering and conditioning at it’s most blatant.. geoengineering (solar radiation management) vindicates accusations ,and solidifies the difference that exists w/ persistent contrails, as described for decades.
    proposals of geoengineering with aircraft & aerosols had finally confirmed the reality that coordinated,concerted aerosol operations are not only possible,but are also seen by many in the scientific community as a viable means to modify,modulate & manipulate global weather,and filter sunlight.(srm)

    i guess if i can cite weather modification stipulations/laws on record..they don’t exist either.

    There may in fact be evidence calling for lower and slower flight so as to diminish the formation of such unnatural clouds. Jets could run pretty fast, and would more often use biofuels less likely to freeze.

  9. The chemtrail conspiracy falls apart once you realize why crop dusting has to happen so incredibly low to the ground…

    • kowalityjesus | Sep 27, 2013 at 8:32 pm |

      chemtrails under the premise that it is being done to affect organisms on the ground, yes that is rather absurd imo. However it could be geoengineering initiated at the highest levels with the utmost secrecy to keep the globe from warming any further. But why wouldn’t they just do that over the damn ocean if they wanted to keep it a secret. It is a mystery to me.
