A look into the theory that the government has learned how to manipulate weather patterns in high security areas to prevent any UFO intelligence from scanning our defenses or sensitive military operations. The existence of UFOs is a phenomenon that intrigues and captivates, yet it generates more skepticism than acceptance. Witnesses of unconventional craft are often disbelieved and even ridiculed. Belief in the existence of UFOs is obviously not yet mainstream, but that may one day change. Over the past few decades, reports of UFO sightings have dramatically increased in North America. Further, these sightings have been observed to be more blatant and even menacing. Some reports even imply that these craft are monitoring our planet. Interestingly, many of these sightings have taken place over military bases. In UFO Weather Shield, A.K. Johnstone, PhD., explores the details of numerous sightings from a scientific viewpoint, including descriptions of craft, luminous sheaths and fireballs. So what, if anything, is the United States government doing about it? Johnstone suggests that military and government agencies have the ability to manipulate weather electromagnetically and with chemtrails to deter unconventional craft. This hypothesis also explains erratic changes in the weather in the last few years. Is the government creating a weather shield to deter UFOs from entering the earth's atmosphere? Take a look at the evidence.
