Ufo/uap (rainbow-like) (witnessed 2), chemtrails for literally nonstop days on end. also witnessed but can not provide proof of nano-particles of metallic(?) what seemed like possiblity trillions and trillions of these particles were visible very clearly after all the chemtrailing, also when these particles were seen anything such as planes became extremely hard to see, almost invisible. these particles were too small and simply did not appear on my camera when i tried to take a picture of it, again the entire sky was covered with this stuff that we're breathing. many people had respiratory infections the next day.
