No “chem-trails”, no vapor trails literally at all. Lots of jets of all types, though…
Use to be when I heard a jet, as I worked in the yard, you could look up and see a very visible vapor trail. Now when you see the jet, the vapor is visible and dissipates very fast. Like on your car when you drive. Yes there is vapor, but as it cools, it just goes away fast…
Interesting. No trails anymore? Ask yourself, “Why?”
