You choosing to ignore an explanation does not equate to no explanation being offered. The reason this happens has been spelt out many times, why do
you think clouds also have gaps and edges? Why can't you understand the simple stuff, like the atmosphere not being uniform and having patches where
it is more or less moist than the surrounding air, but think you have a handle on some complex conspiracy?
I take it you understand the difference between persistent contrails, which require high levels of rh to allow them to persist, and short lived trails
which quickly sublimate in low rh air. Common to both types is that it is freezing cold up there too. All you need is a patch or band of drier or
warmer air crossing the path the plane is flying on and you will have a section of the trail that disappears immediately, while the rest of it
remains. The opposite also happens where a plane not leaving a lasting trail crosses a colder, more saturated, patch and a very short persistent trail
You have a cheek to ask for people to be respectful to you when you called people with an opposing viewpoint to yours "trolls" in your preceding post.
Respect cuts both ways, you know?
