Chemtrails

[Matthew Lewis]

Recognizing chemtrails and contrails?

Simple.

Contrails are short and evaporate quickly.

Wrong. Here's a study from nearly 70 years ago that says otherwise.

Note the top of page 5 (internally numbered page 4) which specifically mentions persistent trails. Since I've posted this study multiple times before in threads you've participated in I can only believe that you have purposely ignored it.

Chemtrails are hundreds of times bigger, emanate from
spray nozzles instead of engines, turn into cirrus clouds,
and do not disappear, but form a hazy, milky sky.

The milky sky is what Dr. Teller proposed to prevent
"global warming".

Simple.

Really? What about all this evidence showing CONTRAILS from times long before "chemtrail" believers say they started, and from before Dr. Teller proposed anything, which show and describe the same things other people say are "chemtrails"?

A post from another person on a completely unrelated forum that mentions proof from 1981 ("chemtrail" believers claim there were never persistent trails before the late 90's)

The Peterson Field Guide Series A Field Guide to the Atmosphere Houghton Mifflin Company 1981.
Has many interesting things about contrails in it.
Photograph page 132 Pl.145 V - Condensation trail from a jet plane that produces its shadow on a diffuse mass of ice crystals extending downward below the contrail and the sun.
(This shoots to hell the dark "chemtrail" BS chemtrailers try to pass and not only shows one in 1981 or earlier but also explains why the phenomenon occurs.
Photograph page 132 Pl.146 - The condensation trail of a jet plane that is growing where the moist air is supersaturated with the respect to ice. This show that the contrail is located below the thin streamers of ice.
This photo is the same as many posted by many chemtrailers that they claim can ONLY BE the result of "chemical spraying". But here we have an example from 1981 or earlier that shows these phenomenon were seen a full decade before claims of chemtrail spraying.
now for some text from page 137:
In this era of high-flying aircraft, condensation trails - contrails - are a commonly observed feature of the sky. Sometimes they are ephemeral and dissapate 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. Sometimes they maintain their integrity as a line of cloud formed in the wake of the rapidly moving aircraft; at other times they develop a series of pendules from which streamers of precipitation are observed to fall.
Contrails are a fascinating subject for study, sufficiently complex to challenge the expert and sufficiently variable to intrigue the amateur observer. Properly understood they yield a wealth of information about the current state of affairs in the high atmosphere, where it is difficult to locate weather instruments. Observed systematically, as a function of time, contrail information is a valuable adjunct to forecasting the weather.
Many other examples and photos showing phenomenon claimed by chemtrailers as only being possible by nefarious ways. In text and photos from 1981 or earlier.
Basically this information shoots down most claims made by the chemtrailers. Shoots down and tramples in the earth.
The Peterson Field Guide Series was sponsored by the National Audubon Society.

1991 photo of a pendulous contrail (or sawtooth as Jack called it in a previous post) with a short explanation of the cause

Clouds before powered flight that look a lot like clouds "chemtrail" believers claim are man made
http://contrailscience.com/clouds-before...dies-1905/

Contrails are formed when heated moisture in engine exhaust
condenses in cold air. There is little moisture left in exhaust
after fuel is burned, so contrails are small.

Chemtrails are particulate matter and chemicals which expand
in cold air, making huge clouds. There is NOT ENOUGH MOISTURE
IN JET FUEL TO FORM CHEMTRAILS.

Wrong.
Same study as above
http://naca.central.cranfield.ac.uk/repo...-l-474.pdf
Page 2 and 3 (internally numbered page 1 and 2)
"When aviation gasoline is burned in an engine, about 1.25 pounds of water is formed as vapor and discharged with the exhaust for each pound of fuel burned."
Anyone familiar with chemistry can tell you that is typical of any hydrocarbon. When burned the exhaust is composed of water and various levels of carbon dioxide and carbon monoxide depending on how completely it is burned.
Again, I must conclude that you have purposely ignored these FACTS.

Chemtrails come from spray
nozzles, not engines.

Simple.

Why do the majority of pictures on "chemtrail" sites purporting to show "chemtrails" show them coming from the engines?
