Chemtrails question for Americans!

Taken from chemtrail FAQ's website

What evidence exists to support a Chemtrail operation?
No concrete proof exists...

So you're kinda not right here.

We deny ignorance don't we?

Anything is possible, well apparently not for you.

Are you calling me ignorant? If I am ignorant then so are you. Yes anything is possible, but when there is proper evidence to suggest that a topic is unplausible then it becomes, IMPOSSIBLE

Originally posted by Paul the seekerI will not give my breath for constant reacting on "meteorologically-experienced" debunkers comments.

Oh I see, because you deny ignorance right? Or is it that you just refuse to believe that I have valid points that discredit the chemtrail theory

You can do some research about the topic, accept that some ppl "maybe" know more than you, or simply refuse it.

I have nothing to proof for you.

Yes some people may know more than me, I dont doubt that. The majority of chemtrail believers, like that guy on your youtube link, base their arguments on what other people say, and photographs. So what you're saying is that chemtrails exist but there is no proof they exist, but still what we see coming from aeroplanes in the sky must be the government spraying harmful substances to poison/ mind control/ sterilise us, because that is more likely than hot exhaust from an aircraft entering a super cooled environment and condensing?

Paul, the problem is that no one can post reports of chemtrails unless they know what chemtrails look like. And no-one as yet has come up with any means of identifying since all chemtrails apparently look like this:

Or this:

Or this:

All of which are normal aircraft contrails and cirrus clouds

How does one identify chemtrails from the ground?

Chemtrails have their usual facials, such as seemingly staying and expanding.
I have seen trails that were very broad but disappeared after about 10-20 seconds, while others in the same sky would just stay like clouds and continue expanding slowly.

Maybe before looking for chemtrails you should familiarise yourself with the behaviour of normal contrails? Which can last for hous ands spread out to cover the whole sky

I will say this. For the first time in my forty years, here in TN, we had chemtrail spraying all summer long. This was a first for me, I repeat. I have never seen anything like this ever before. Before researching this subject, I could tell you they caused high pressure...because that was what we had all summer...with the corresponding lack of rain. I started making time lapse videos of the chemtrail spray and what you can tell (very clearly) is that the strength of the winds corresponds to amount of spraying. I've noticed that if a line is sprayed above you the wind starts blowing almost immediately (even on a relatively windless day).

Oh really? Wow, I never wouldve guessed that. This is coming from a pro chemtrail website. See you chemtrailers, no evidence

I saw a chemtrail yesterday. Over my house. It spread out very wide and stayed up for nine minutes before turning blue and vanishing. This morning my little brother got the measles.

This is obviously not a contrail, it’s far too low and the trail is dropping too rapidly.

It’s a Boeing 747-100 “Supertanker”, modified by Evergreen Aviation, the only one of its kind. Specifically designed for fire fighting. That’s it dumping water.

Here’s a VIDEO of it in action, titled “B747 chemtrails”. It’s interesting reading the comments, as the first comment correctly identifies what it is, and then everyone else just ignores that and starts speculating.

Here’s another photo you see in “chemtrail” videos, with the implied suggestion that it’s some kind of evil spraying device:

Actually it IS a spraying device, but quite innocuous. It’s used by the air force to test icing of planes in flight. See:

Do contrails sometimes persist and spread out?

Yes, see the Encyclopædia Britannica article on vapour trails (contrails):


Contrail, streamer of cloud sometimes observed behind an airplane flying in clear, cold, humid air. It forms upon condensation of the water vapour produced by the combustion of fuel in the airplane engines. When the ambient relative humidity is high, the resulting ice-crystal plume may last for several hours. The trail may be distorted by the winds, and sometimes it spreads outwards to form a layer of cirrus cloud.

Also see “A Field Guide to the Atmosphere“, by Schaefer and Day, 1981:

“Sometimes [contrails] are ephemeral and dissipate as quickly as they form; other times they persist and grow wide enough to cover a substantial portion of the sky with a sheet of cirrostratus“ (Page 137)

Are spreading contrails a relatively new thing?

No, it has been exactly the same for decades, the only change has been the size of jet engines (producing bigger contrails), engine efficiency (burning fuel more efficiently creates more water vapor) and the amount of air traffic (producing more contrails).

See, for example, all these articles on contrails. In particular the one titled “Airborne Observations of Contrail Effects on the Thermal Radiation Budget“, from 1970:

The spreading of jet contrails into extensive cirrus sheets is a familiar sight. Often, when persistent contrails exist from 25,000 to 40,000 ft, several long contrails increase in number and gradually merge into an almost solid interlaced sheet.
[….]

Contrail development and spreading begins in the morning hours with the start of heavy jet traffic and may extend from horizon to horizon as the air traffic peaks. Fig. 1 is a typical example of midmorning contrails that occured on 17 December 1969 northwest of Boulder. By midafternoon, sky conditions had developed into those shown in Fig. 2 an almost solid contrail sheet reported to average 500 m in depth.
