What are chemtrails?
water vapor formed by the vortical flow of air off the wings of aeroplanes.
I believe those are contrails. Chemtrails are the supposed chemicals which are dropped from the plane to look like contrails.
No that's what crazy people think they are, what they really are is water vapor.Chemtrails are contrails.
Also, see my sig for tinfoil hat goodness.
The funniest thing about this particular topic is this: You're and evil military or corporate power with seemingly unlimited funds and the best minds at your disposal. You want to poison the people/change the weather/influence the outcome of idol. You load up your giant fucking jet and proceed to spray during daylight in unlimited visibility in full view of looneys with cam-corders. Brilliant.
