How many airline pilots do you know? I know a couple personally and they would never poison people with chemtrails. I doubt you know what they are in reality.

I know pilots too. I also know a few airline mechanics but that doesnt mean they are supposed to know about governement and military operations. They have no clue very much like you and most of the public. But with a little curiosity and desire for truth you can find out FACTS instead of making acusations about other people just speculating in what they believe they are.

I haven't had the chance to watch this yet, (it's next on my list!) but I trust this site and Dane Wigington to do their research...

And I also don't think that every pilot is spraying harmful chemicals into the air; however it is happening and I believe we have the right to know what exactly it is and why.
