Literally have only seen one chemtrail while living here in Panama. I wouldn't have thought that was what it was had I not seen the jet at the head of it. That was during dry season. We do not see any type of plane or jet in our sky where we live...ever. There is even a (built by Noriega) air strip very close to our house. Never seen a plane there although I've heard they do land small ones on occasion. Anyway, interesting article. It's crazy what the government is willing to do. Crazy that changing the jet stream can cause such issues!! "Nuclei" must be the word of the day - second time I've seen it today. ;)
