Hot jet exhaust meets cold atmospheric air at altitude and guess what happens-———————————————>contrails!

Oh, that's SO what "they" want you to believe ...

How come propeller airplanes never made those trails? Or birds? Or covered wagons? Huh?

What do you think we are? Stupid?

Here’s a page full of propeller-driven airplanes causing contrails.

During WWII.

Actually propeller planes did make contrails.
B-17 onward.

That’s how we won the war, Chemtrails over Germany and
japan.

[tet68]

The covered wagons didn’t create Chemtrails because the
canvas cleverly broke up the slip stream...
Although if you wormed your mules in the morning it
was probably a good idea to walk in front for a while.

Oh BS! B-17’s, B-24’s, B-29’s, etc all left contrails in WW2.

IMO, one would have to be a drooling, mouth breathing, inbred moron (just like jessie ventura) living in their mom’s basement to believe in “chemtrails” or any one of the other conspiracy nutjob stories.
