The article is against the chemtrail theory not for it. It explains how simple contrails are not how these whackos see them as.
Condensation trails disperse differently than “chemtrails”. Chemtrails may be spectromically analyzed as being a salt, in some cases a barium salt which may ionize and disperse over a large area, yet still appear opaque such that it casts shadows. Several to a hundred “chemtrails” may be dispersed in clear skies such as to turn the entire visible sky into an overcast weather activity, while condensation trails generally disperse within a mile past the aircraft at subsonic speeds in lower elevations above 20000 ft depending on temperature and pressure and relative humidity.
Some have suggested chemtrails are communications conduits or might be conduits for phase array synthetic aperature radar systems to increase their ‘synthetic’ focal lengths.
The time of chemtrail appearance in the late 90s was not coincident with any jet aircraft operational characteristics which might coincide with natural condensation formation.
Many USAF flag rank officers at the time in command billets and research billets recognized the phenomenon but were not cognizant of any natural phenomenon explaining their appearance.
Additionally, the natural environmental damage caused by such prolific activity associated with commercial jet aircraft operations could easily justify significant regulation on the industry, unless protected by either Executive Order or national defense and homeland security.
Their appearance also coincided frequently with operational planning milestones such as 15 and 30 day increments after and preceding major international affair decision points, which lends itself as consistent with the conspiracy theories associated the phenomenon with intelligence or military operations after Open Sky treaties were implemented.
Sometimes the best security is hiding in wide open with eyes wide shut.
