If you loosely define chemtrails as “a trail of chemicals” then almost everything has chemtrails. Fuckkin ants have chemtrails, it’s how they communicate and navigate.
Chemtrail conspiracists literally think that airplanes are full of 55 gallon drums of chemicals with the express purpose to harm or feminize the populace to prevent people from opposing the government.
Incorrect. The condensation you are seeing in the air is a product of combustion. If no water was added to the air, then compressing it and decompressing it would not create a cloud or vapor trail.
Edit: Fine. It’s mostly incorrect.

Yes, the lower pressure can create a very temporary contrail, and in rare situations where the engine exhaust also cools down below freezing before it reaches ambient pressure, ice crystals can form and create a longer more visible contrails. Realistically, what you are seeing in a contrail is water vapor from combustion. Seriously, H2O and water are the largest products of combustion, and it’s like 99% of what you are seeing behind aircraft.
