Now there we're talking about cloud seeding. That is at least mostly real.

If I understand correctly, the object is to spray chemicals into the air which strongly encourages moisture to condense into clouds, either blocking sunlight or causing rain. The USAF experimented with this during the Vietnam war to some success, it's not exactly the cartoon idea of "Airplane flies by, airplane farts, there's a rumble of thunder and an instant summer rain shower". Though for various reasons to include "the chemicals you have to spray to make this work aren't very nice" it's probably a bad idea. I gather that's what the legislation in question is actually about, and it's honestly not a bad idea to regulate or ban this practice.

The word "Chemtrail" isn't associated with that, it's tinfoil hat ivermectin sucking 5G fearing moron talk for "the airlines are spraying chemicals that make you vote Democrat. Wake up sheeple." Which is 1. complete and utter donkey shit, 2. makes conversations about cloud seeding worse, and 3. makes conversations about General Aviation still using leaded gasoline worse.
