Hot take: I used to think chemtrails were real, but a pilot friend in Denver broke it down for me
For years I bought into the whole chemtrail thing. Then my buddy who flies 737s out of Denver told me something simple. He said the white lines are just water vapor freezing at 30,000 feet, and they last longer when the air up there is humid. He showed me his flight logs and weather data from one trip. I checked it myself online and it matched. Now I feel kind of silly for arguing with people about it. Has anyone else changed their mind on this after talking to someone who actually does the job?
