 A lot of people have noticed this while watching a plane leave grid-like patterns above their houses in the countryside. There's no trace of the plane on flight radar websites. Ghost planes. So Air Traffic Control and the government and military are all involved. Since they weren't, an unregistered plane not appearing on flight radars would be taken out within minutes by Air Force. You have to realize there are thousands of people involved, but a lot of these people believe chemtrails are in the public interest.
