Chemtrails?  Yes, chemtrails.  They are real.  I believe that some of the chemtrail programs have something to do with these craft.  At first, when I thought they were all military, I believed that chemtrails were mid-air refueling.  I could see and record the invisible craft inhaling the chemtrail lines.  I still hold this as an option, but I now also believe that some of the craft are not necessarily military,  and that chemtrails are poisons to the "natural" craft above.  Watchers?  Air conditioners?  Fallen Angels?  Annunaki?

Weather control?  Maybe exactly so, but what is the weather?  What really constitutes a cloud system.  In many cases, it's a system of triangular craft...
