I used to post here weekly about contrails being poison, but last Tuesday I watched a NASA livestream from a plane window in Denver and saw the exhaust freeze into ice crystals in real time. Then my buddy pulled up the flight radar and we tracked the exact same path. Has anyone else had a single piece of footage override their whole stance?
That flip moment hit me the same way a couple years back, except mine was a timelapse some guy shot from his backyard in Montana over like six hours. Watched the trails spread out and thin into cirrus exactly how the physics says they should. What really did it was when someone in the comments pulled the raw weather data for that exact day and the humidity at flight level matched up perfect. Once you see it line up with the actual conditions, you can't unsee it. Not saying I trust everything the gov says, but ice is ice.
