Robert Salas, a retired United States Air Force officer, witnessed firsthand a UAP (unidentified aerial phenomenon) while visiting and disabling nuclear missiles. He shares his experience as well as the many incidents of similar visits during the last eighty years that have been covered up. In 1969, the US Air Force issued a statement that read‚ “No UFO reported, investigated, and evaluated by the Air Force was ever an indication of threat to our national security.” This statement has been proven untrue by the testimony of many military officers and airmen and the documentation of incidents involving UFOs and nuclear weapons, testimonies of which the US Air Force was fully aware. UAPs and the Nuclear Puzzle details many of these testimonies—some for the first time.
