Chemtrails, trails of aerosolized chemicals secretly released from aircraft over civilian populations, were dispersed without consent or warning over US cities and towns in the early 1950s.
The US Army Chemical Corps conducted Operation LAC(Large Area Coverage), a program to test what it would be like to drop extremely dangerous bioweapons over enemy cities by dropping less dangerous carcinogens like zinc cadmium sulfide(ZnCdS), over US civilian populations without knowledge or consent, and without following up on the long-term health effects of dropping ZnCdS on US civilian populations.
NIH recommends the Army conduct tests on the toxicity of ZnCdS since it can get stuck in the lungs
The Army was like, nah.
YSK because as nonsensical as some later chemtrail theories became, the conspiracy of secret chemicals dropped from aircraft onto US civilians without knowledge or consent did occur, according to the US government and military branches that conducted the tests.
again, your evidence did nothing to refute the US government's record of project LAC, links of which are provided above.
nothing theoretical here.
rule #1 is to provide evidence for your claims.
please note rule #5 as well, which is to be civil to others.
