Hello All, I hope you are doing great!
Some observations:
If what we see are just contrails, then why do they fall at sunset? Observe that on days with heavy trails the fake clouds that are created by the EDPs generally fall apart / disintegrate at sunset. What is is about sunlight that keeps the EDP ‘clouds’ intact?

And speaking of sunset, if the long lines that persist from horizon to horizon are simply “Contrails”, then why don’t we see fresh ones at night? And why aren’t there more of them at night when temperatures are cooler and more conducive to contrail formation? I’ve only seen one at night and now I can’t find the pic, dang it, lol.

OK, more to follow, this is my first blog!
E-Cheers!!
