i'm not saying i know what they're spraying,
Whoa, whoa, whoa. You are putting the cart before the horse. I've not seen you establish that anyone is actually spraying anything yet. You've jumped from "some contrails last longer than others" directly to "someone is spraying something". That is a huuuuuge leap. You need to make the connection. Walk us through it.
i just know it can't be good.
You have repeated this claim that prompted this thread. I ask the same question I asked before - how do you know what you think you know?
no one can seem to say what exactly it is that stays in the air and doesn't act like a normal condensation trail.
to the contrary, everything I have seen about contrails says there is variability in how long they last depending on weather, temperature, altitude, and type of engine involved. It could even be affected by the fuel mixture <-- little bit of my own conjecture there.
when is it EVER a good thing when something is being released into the atmosphere?
how about when plants release oxygen?
how cold it is, how high up they are, but not all of these planes i and others see are super high up, yet they still leave the lines.
Have you ever tried to answer these questions by doing any research? There are
answers for these questions and they are not difficult to find.
...it seems to be kicked into overdrive at times with heavy streaking in the sky, yes, i'm paying attention to that as i have to figure out what my triggers are,
Are you aware of confirmation bias
? Unless you are keeping rigorous records and applying statistical methods to them, you are probably unable to detect a pattern.
water vapor goes away in a reasonable amount of time...
you mean humidity? What about clouds? They are water droplets that have condensed out of the atmosphere. They don't just "go away". Have you ever taken earth science?
Just for technical accuracy, water vapor is a gas and is invisible. When you see clouds or contrails, they are made of fine liquid water droplets that have condensed, no longer a gas.
these trails don't just go away.
so what is it then?
I would suggest you not leap to alternatives before at least trying to understand what the actual process is.
You keep saying you know things, yet you have not answered my question as to HOW you know any of these things. Come on, keeta. I'm trying to help you here. But I need you to work with me.
Water vapor condensation does not always dissipate rapidly.
especially if it has turned to ice. Which it often does at -40°F. Which it often is at very high altitudes.
is where i live, the wind RARELY stops,
Do not assume ground conditions reflect the conditions at 30,000ft. They are, in fact, very different.
but i don't believe it's just water vapor & exhaust,
Based on what? What would it take to convince you otherwise? Why do you struggle to reject every answer other than the one you already believe? This is not rational. Expected, but not rational.
