This is what a chemtrail looks like when the atmosphere is calm at higher altitudes. If you think otherwise, let me know. This chemtrail, like most, is comprised of coal fly ash which contains many harmful chemicals. One of these is aluminum which is responsible for the rapid rise of Autism for the last twenty years. You can check this out on the internet. This photo was taken on March the second, this year. I estimate that it was between 4 to 8 thousand feet AGL.

Doesn't look like any chemtrails I have seen. And they have not been proven to cause autism.

Looks like a natural atmospheric occurrence to me. It looks similar to an altocumulus cloud formation.

They look like Cirrus clouds to me.
(High altitude wispy clouds.)

Yea, there's LOTSA STUFF on the internet, doesn't necessarily mean it's true by its existence.

I'll deny it.

Beware of woke Russian pilots dropping chemically loaded objects from their planes that fall to the earth. Those are far worse than those thin cirrus clouds!

For someone who has been "involved in aeronautics since I was fourteen years old", I am saddened that you believe in the chemical trail conspiracy...

Making the blanket statement that Aluminum in fly ash IS responsible for the Autism rise in the last 20 years is going to be pretty hard to defend.

So, what causes these chemtrails and what's the difference between a chemtrail and a contrail?

Yes, Cirrus clouds, high and usually tiny ice particles strung out in long thin lines by the prevailing winds at that altitude.
Cirrus clouds form at 8-12KM altitude (around 25,000 to 40,000 feet).

Some people believe that chemtrails are pollutants spewed out of jet engines (or sprayed) and other flying craft (and some far out people believe it is a deliberate Gvt project).

I on the other hand hold with what they are seeing are either clouds, like here, sometimes smoke downwind of a large brush/forest fire etc. or "contrails" which are water and or ice particles condensed out of the atmosphere by the passage of aircraft. Some times with a bit of engine exhaust.

I have seen pictures of WW II bomber formations with contrails from the engines, wing tips and even spiral ones from the tips of the propellers. The spirals only keep their shape for a short time and then wind or the passage of other bombers in the formation break them up and they become streaks behind the aircraft.

I must repeat that my photo shows the chemtrail at 4000-8000 feet of altitude. Cirrus clouds occur only in the stratosphere. My career included two NASA programs: The Surveyor moon lander at Goldstone Tracking Station in California and the Apollo command module simulator at MSC Houston.

You might have noticed the distances between the bands of the chemicals (actually minerals) are very regular and not what one would expect in clouds or contrails. Do not get fooled by Google's description of contrails whenever you try to get info on chemtrails. They are B.S. spreaders of the first order.

How do you know/measure the altitude?
