We need to uncover the magnitude of the problem. Could be tests,, might be widespread.

• Chemtrails
  • "Taggants"--Quantum Dot Nanoparticles -- Fluorescent Nanoparticles responsive to infrared and/or hyperspectral imaging, being sprayed over battlegrounds and other locations in order to bind to various assets, for the purposes of monitoring their movements via satellite and drone imagery^^ [qd1] [qd2] [qg3] [qd4] [qd5] [qd6] [qd7] [qd8] -- thx /u/MurrueLaFlaga ! and their fantastic copypasta
  • Cloud Seeding : release of silver iodide, dry ice or salt to create precipitation. Technically similar to chemtrails but not part of the 'chemtrail conspiracy', this is included as a distinction of the known primitive 'weather modification' technique. It's here also to demonstrate the motivation, and technical evolution of what would become chemtrails ('what else can we spray?').
  • Operation Big Buzz : Bugs. Big Buzz was a U.S. military entomological warfare field test conducted in the U.S. state of Georgia in 1955. The tests involved dispersing over 300,000 mosquitoes from aircraft and through ground dispersal methods. [U]
  • Operation Dew : Operation Dew refers to two separate field trials conducted by the United States in the 1950s. The tests were designed to study the behavior of aerosol-released biological agents. Operation Dew took place from 1951-1952 off the southeast coast of the United States, including near Georgia, and North and South Carolina.[1][2] Operation Dew consisted of two sets of trials, Dew I and Dew II. Operation Dew I consisted of five separate trials from March 26, 1952 until April 21, 1952 that were designed to test the feasibility of maintaining a large aerosol cloud [ of zinc cadmium sulfide ] released offshore until it drifted over land, achieving a large area coverage. Dew II involved the release of fluorescent particles (zinc cadmium sulfide) and plant spores (Lycopodium) from an aircraft. Dew II was described in a 1953 Army report which remained classified at the time of a 1997 report by the U.S. National Research Council concerning the U.S. Army's zinc cadmium sulfide dispersion program of the 1950s.
  • Operation Ocean Spray : Bacteria. Operation Sea-Spray was a U.S. Navy secret experiment in which Serratia marcescens and Bacillus globigii bacteria were sprayed over the San Francisco Bay Area in California. [U]
  • Operation LAC : Operation LAC (large area coverage) was a US army chemical corps operation that dispersed microscopic zinc cadmium sulfide (ZnCdS) particles over much of the United States. The purpose was to determine the dispersion and geographic range of biological or chemical agents. Anecdotal evidence suggests there were adverse health effects--of course mitigated by US gov agency reports which are to be trusted always (911 NIST report, Warren report). The wikipedia article continues, "the use of ZnCdS remains controversial and one critic accused the Army of "literally using the country as an experimental laboratory"". This is solid proof of chemtrails and because of the widespread scope of the dispersal (most of US), chemtrail doubters such as topmind types have no leg to stand on anymore.
  • The Fluorescent Particle Trials : Toxic Metals. A UK Ministry of Defense report included 'The Fluorescent Particle Trials', [in which it] reveals how between 1955 and 1963 planes flew from north-east England to the tip of Cornwall along the south and west coasts, dropping huge amounts of zinc cadmium sulphide on the population. [U]
  • Meteorological 'Blob' from R-188 Military Chaff : Aluminum. "The chaff was visible on their radar for more than nine hours, and the news stories lingered even longer. "Officially, Redstone Arsenal disclosed that it was a military test using RR-188 military chaff," Havin said, referring to aircraft used to spread a cloud of aluminum-coated silica in the case of RR-188. The cloud can confuse radar-guided missiles, for instance, so they miss their targets. (thanks MKULTRA_escapee) [U]
