The contrails (including persistent ones) contain water but also different kinds of emmissions from the airplane, like sulfur dioxide and other gases. Not sure if it differs very much from typical car exhaust gas though, but nobody wants to get any exhaust on themselves.
The persistent contrails are persistend due to environment the contrail is in. You can even see two planes flying in the sky while one is leaving a short-lived contrail and the second one has a persistent contrail. This might seem weird, but the distance of the two planes can be kilometers/miles, even though you see them both at once. They might be flying in completely different altitudes, but it's hard to know when you're standing on the ground :)
Hearing about microplastics is special! Not sure if those should be in the contrails, but microplastics are a constantly growing issue. We're having microplastics in the oceans, lakes, in our waste water, at worst even in our drinking water. There's microplastics in the ground and we might have some microplastic-particls in the air too. I would be surprising if there'd naturally be microplastics in the contrail, but microplastics can be found almost anywhere, so that alone is terrifying.
Mainstream media is not discussing contrails much, but they actually are doing that! The main issue with persistent contrails is how it affects the environment, as the contrails are "man made clouds" and having a lot of persistent contrails might affect the climate. Scientists in the field are trying to find ways to avoid persistent contrails.
I've been watching them for years. If you do time lapse videos you will see they are not normal contrails. Even the rainbows that sometimes form in them are weird looking. I would not want to be out on a day like the last photo.
Well all of them are actually normal, it depends on multiple things if the contrails are persistent ones. If I'm not wrong, they're more common in higher altitudes and flying in higher altitudes is more fuel-efficient for the planes.
The main issue with persistent contrails is that it increases the amount of clouds as "artificial clouds", so aviation industry and scientists are trying to find ways to reduce amount of persistent contrails.
There are some ways to control weather on some level, but flying airplanes in hopes of getting persistent contrails is not any way an effective way to control weather.
I heard of persistent contrails in the US long before I observed them in Canada. In fact, I would watch our sky and see nothing different than I had seen all my life. Then, in the summer of 2013, which came after the winter of 2012-2013, which almost didn't exist here, they appeared.
A friend of mine, a PhD whose undergraduate degree is in chemistry, and who has written books that feature them, spotted them here the same summer. I have looked up at the sky every day of my life. I watch planes criss cross the prevailing wind on the west side of Ottawa in the morning and I have noticed how they aren't up there on long weekends. Instead of researching chemtrails, try searching for geoengineering to see the scientific literature on them.
In every NATO country, I understand. There seems to be a little less of it lately although not today. Do you realize it is no longer a "conspiracy theory?" See this article from August.

What are normal contrails? Short lived ones, the persistent ones which stay in form or the persistent ones which spread out?
The short lived ones. I call the other ones chemtrails.

Increasing the amount of clouds can be really handy if you're a government agency that is experimenting with weather modification and control.

Yes, geoengineering is what I believe they are doing with these persistent contrails.
It has been banned by the UN except for experimental purposes. You don't ban something that doesn't exist.
It's been banned, and yet, you see them everywhere. Lots of experiments going on...
In every NATO country, I understand. There seems to be a little less of it lately although not today. Do you realize it is no longer a "conspiracy theory?" See this article from August.
Yes, I know that it's a real thing, but a lot of people still don't believe it, so they call it a "conspiracy theory".
