Another huge logic fail with any conspiracy argument that rises to the levels of 9/11 and so called chemtrails is exactly what Aerozepplin said a few posts above. It would involve tens of thousands of people remaining absolutely secret about what is going on. The whole idea is laughable. History has proven time and time again that Governments anywhere in the world are notoriously hopeless at keeping anything strictly confidential for any period of time. Comes down to human nature.
