Operation L.A.C.

It's well known that Wikipedia is an implausible or superficial encyclopaedia. This applies particularly to Wikipedia Italy, whose terms "hot" are established and controlled by frustrated and failed fellows known as disinfo-agents (or debunkers). However, even the infamous Internet encyclopaedia can not abstain from reporting certain events. For example, we remember "Operation L.A.C. (Large Area Coverage), a criminal trial designed to test the dispersion of Sulphide cadmium zinc in wide areas of the United States of America. The operation was successful: the toxic cloud was spread to cover a very large region of the U.S.A., encroaching into Canada and Mexico too. The experiment was not an isolated incident, but only one of the first and many tests which culminated in the daily activities of very broad and global poisoning known as "chemtrails”.
Earlier tests
There were tests that occurred prior to the first spraying affiliated with Operation L.A.C. The Army admitted to spraying in Minnesota locations from 1953 into the mid-1960s.
Operation
Operation L.A.C. was undertaken in 1957 and 1958 by the U.S. Army Chemical Corps. Principally, the operation involved spraying large areas with zinc cadmium sulphide. The U.S. Air Force loaned the Army a C-119, "Flying Boxcar", and it was used to disperse zinc cadmium sulphide by the ton in the atmosphere over the United States. The first test occurred on December 2, 1957 along a path from South Dakota to International Falls, Minnesota.
The tests were designed to determine the dispersion and geographic range of biological or chemical agents. Stations on the ground tracked the fluorescent zinc cadmium sulphide particles. During the first test and subsequently, much of the material dispersed ended up being carried by winds into Canada. However, as was the case in the first test, particles were detected up to 1,200 miles away from their drop point. A typical flight line covering 400 miles would release 5,000 pounds of zinc cadmium sulphide and in fiscal year 1958 around 100 hours were spent in flight for L.A.C. That flight time included four runs of various lengths, one of which was 1,400 miles.
Specific tests
The December 2, 1957 test was incomplete due to a mass of cold air coming down from Canada. It carried the particles from their drop point and then took a turn northeast, taking most of the particles into Canada with it. Military operators considered the test a partial success, because some of the particles were detected 1,200 miles away, at a station in New York state. A February 1958 test at Dugway Proving Ground ended similarly. Another Canadian air mass swept through and carried the particles into the Gulf of Mexico. Two other tests, one along a path from Toledo, Ohio to Abilene, Texas and another from Detroit, to Springfield, Illinois, to Goodland, Kansas, showed that agents dispersed through this aerial method could achieve widespread coverage when particles were detected on both sides of the flight paths.
Scope
According to Leonard A. Cole, an Army Chemical Corps document titled "Summary of Major Events and Problems" (1958) described the scope of Operation L.A.C. Cole stated that the document outlined that the tests were the largest ever undertaken by the Chemical Corps and that the test area stretched from the Rocky Mountains to the Atlantic Ocean, and from Canada to the Gulf of Mexico. Other sources describe the scope of LAC varyingly, examples include, "Midwestern United States", and "the states east of the Rockies". Specific locations are mentioned as well. Some of those include: a path from South Dakota to Minneapolis, Minnesota, Dugway Proving Ground, Corpus Christi, Texas, north-central Texas, and the San Francisco Bay area.
Risks and issues
A large body of evidence exists of ZnCdS having adverse health effects as a result of LAC. However, a U.S. government study, done by the U.S. National Research Council stated, in part, "After an exhaustive, independent review requested by Congress, we have found no evidence that exposure to zinc cadmium sulphide at these levels could cause people to become sick." Still, the use of ZnCdS remains controversial and some critics have accused the Army of "literally using the country as an experimental laboratory".

"Operation L.A.C." (Large Area Coverage), fu un esperimento dell'esercito statunitense che fu attuato con la dispersione di particolato a base di solfuro di cadmio zinco (ZnCdS) su gran parte degli Stati Uniti. Lo scopo era quello di determinare la gamma di dispersione geografica di agenti biologici o chimici.
