On friday, one of our other members posted a thread about chemtrails over Oklahoma. He took pcitures and stuff. Not so far from where yorue at.
I also saw chemtrails being made and made over south east seattle metro area.

Would it be possible to spray something into the exhaust at that altitude? Yes but whatever would be dispersed into the air at that altitude would become so diluted by the enormity of the atmosphere that my guess is that it would be very ineffective at reaching the population below.
