Even Indy cars with their speeds exceeding 200 mph produce contrails, another thing which shatters the silly idea that they were first visible in the 1990s in the sky.
Once you delve into chemtrail fantasists’ bizarre websites, you get a wide spectrum of different kinds of misconceptions, misinterpretations, and outright falsehoods. The oddest is that people seem to think that contrails are some sort of new phenomenon, when as I just pointed out, we’ve been seeing them in the sky since planes have been flying at high altitudes. People apparently don’t remember seeing contrails when they were young, but that just testifies to the fallibility of human memory, because the photographic record of ordinary contrails goes back to before the 1930s. People don’t remember seeing contrails coming from their jetliner when they fly, but then they can’t look behind the plane in any commercial flight, so they can’t see the contrails—but they are there just the same.

I love the chem-trail theories. I mean you have to admit sometimes they just disperse and sometimes they just cover the skies.
I can understand the plume coming out of a jet engine at the point it for lack of a better term, becomes visible from the ground may be roughly the diameter of the engines exhaust. What is that? 3 or 4 feet in diameter? That is a lot of area in a 3 or 4 foot diameter circle. A=Pi x R squared.
If the wind conditions are right all that exhaust could flatten out and what looks like a 3 foot wide, 1 dimensional swath from the ground but in reality is 3 foot diameter, 2 dimensional could turn all the area of that circle into a thin flat layer of exhaust.
But sometimes it seems the con/chem trails are hard to justify.
