Let me tell you something anon. I am a airline pilot. 30+ years. Your post is about the most inane, uniformed illustration of ignorance I've seen on this bullshit issue of "Chem-Trails".
The commercial fleet of airliners, no matter the carrier, no matter the type of aircraft, is NOT being used to spray chemicals into the atmosphere. Period. There is no "BIG CONSPIRACY by the manufacturers Boeing, Airbus, Embraer, Bombardiier, all of them, to poison the skies. There is no "switch" in the cockpit that says "Chemical Discharge". Chemicals are not being laced into Jet A fuel. The only thing being exhausted into the air is the same thing that comes out of your car exhaust.
In the remote possibility that you have not been paying attention, air traffic is down because PEOPLE ARE NOT FLYING due to muh corona.
You seem well meaning and sincere. I'd be happy to answer any question you have on why you see these "contrails". Educate yourself please.
