Author Topic: I need a WWII photo with contrails. (Read 1077 times)

Preferably a whole sky filled with contrails from a fleet of bombers.

My co-worker is a recent victm of a chem-trail craze and I want to prove to him that planes used to leave long persistent trails long ago.

You are obviously a part of the plot to convince people that such "contrails" are a normal byproduct of high altitude flight. Do you really think that SARS, mad cow, and ebola just spread all by themselves?

Actually that's pretty close to what the chemtrail kooks believe.

^^^ B-24's spreading chemical agents over Germany, 1945.

No, they are spreading mad cows...

Yes part of the secret 8th AF chemical warfare program run by Curtis Lemay.

I recall reading that 2% of cloud cover can be attributed to jet contrail origins.

Given that clouds are white and reflect sunlight back into space and given that we are experiencing global warming (human assisted or not, global warming is happening) anything that helps cool the planet is a good thing.

Ergo, jet contrails are a good thing.

I do not care if the government is producing chemtrails or not - at least not in that discussion.
I am just trying to prove that the "chemtrails" look exactly like a regular contrails - which could be miles long and last for hours or days.

He seems to believe that a regular contrail only extends few dozen yards behind a plane and quickly dissipates - which contrails often do depending on temperature/humidity.

So that picture is not good for my purposes bacause contrails on it are of such quickly-dissipating variety. Thanks, mietla, but I need a different one.

It is a very solid hypothesis that regular ice ages on Earth are produced by periodic increase in cloud cover - which is in turn is caused by the solar system traveling through parts of the galaxy with more interstellar dust, which serves as condencation catalyst, just like plane exaust.

Yep, persistence of contrails is directly related to humidity and presence of nucleation catalysts.

Keep looking, there are photos from WWII showing the whole sky covered in persistent contrails.

Almost every day I can go outside and see a contrail extending from horizon to horizon.. how persistent do you need them to be miko?

No its the other way around. While the clouds whiteness reflects some from the sun, it reflects many times more from the earth. The polar caps are the "good" reflectors, while the clouds are the "bad" reflectors because the clouds tend to keep the heat inside the atmosphere.

Those will not help me - they may as well have been produced by nefarious government tankers spraying stuff at high altitude.

I needed trails that were there for at least a few minutes.

About that 2% thing, I think the study was from the post-9/11 period when the entire US became a no-fly zone. Scientists took advantage of the lack of contrails and made a correlation to air temperature and cloud coverage.
