I already have if you read some of my posts on the matter. If you'd like to differ on something specific I've argued, please feel free to recite it here. I'd be happy to debate the specifics with you. To be honest, it would be refreshing to focus on one fact at a time, rather than all this hearsay/conjecture, random links, and purported "insider" posts.
I'll start: Chemtrail believers suggest all contrails dissipate in a matter of minutes (i.e. no contrails can persist or spread out). Regardless of whether the Conspiracy is true, this is an irrefutable falsehood because:
1.) Contrails have done this throughout history (going back to the 1940s and probably earlier).
2.) Contrail (water/exhaust vapor) can persist for many hours and even become cloud cover depending on the temperature and relative humidity that the trail was formed in.
3.) Size and frequency of contrails has increased exponentially with the amount of air travel currently seen today and the size and efficiencty of jet engines in use today.
In fact, I would say nearly all of the reports of "thick trails" are attributable to modern day aircraft engines in low temp/high humidity altitude layers. How fuel efficient an aircraft engine is affects the amount of heat and water emitted in the exhaust plume. Thus, a more efficient engine (better fuel burn) produces larger plumes (more H20 vapor).
But you never hear any of the chemtrail people talk about this. Why? They are either ignorant of these facts or choose to ignore them. Therefore, I wouldn't even begin to entertain an "insider" as credible until they can at least acknowledge these very basic fundamental truths.
