Here is a patent for chemtrail given to Hughes. US patent #5003186 Google it and look at the actual patent for adding 10 micron sized Aluminum Oxide to jet fuel. No need for aerosols, straight dispersal from exhaust. The purpose of this substance is to reflect infared spectrum heating from the sun into space to mitigate global warming. I would like to hear any input on whether there is a HAARP connection in respect to weather modification. Some strange radar images accompany storms, with clear organized design appear. Using HAARP to agitate the atmosphere where this micron sized metallic material is, would be not hard to imagine. Hope the NSA doesn't see this as some threat to national security, but only interested curiosity.
