Contrary to rumors of “conspiracy theory”, the Department of Defense first published “Chemtrails” in 1990 as the title to a chemistry course for new pilots attending the esteemed US Air Force Academy. The term “Chemtrails”, and its implied meaning was eventually adopted by civilian observers to describe unusual jet contrail emissions.

In 2001, US Rep., Dennis Kucinich introduced HR 2977 “Space Preservation Act of 2001”. The text of the Bill defines Chemtrails as an exotic weapon.

To their credit, the Oxford dictionary provides an accurate description of chemtrails even if they failed to list the US DoD as the original publisher.
Oxford Dictionary Defines “Chemtrail”
” a visible trail left in the sky by an aircraft and believed by some to consist of chemical or biological agents released as part of a covert operation. “
The purpose of this post is to establish the term “chemtrails” was invented by the DoD and USAFA. However compelling, we resist claiming that the title and/or content is directly linked to the covert aerosol geoengineering and “chemtrails” operation that has been infecting planet earth for the past quarter century. The course content, however suggests an intent to manipulate atmospheric chemistry and could be construed as a course requirement for pilots who could be engaged in deploying chemicals into the atmosphere.
