Guys I know its a far cry from what you usually discuss here but I came across some videos on youtube about the Chemtrail conspiracy... What are you guys thoughts on this? Are these people on crack or what???

The conspiracy basically states for those unfamiliar if any are unfamiliar that what we usually call "contrails" are actually "chemtrails" that is a trail of chemicals that has been purposefully dumped on us for some reason...

I figured I'd ask level-headed seasoned airline pilots what their thoughts were...
