To look at the facts without accepting any level of speculation, we can draw one conclusion definitively from the phenomenon of UFOs. We can conclusively and undeniably prove without an inkling of doubt that whatever their source, UFOs are commonly reported on a daily basis around the world. So even without assessing whether or not its source is beyond our current understanding of the widely accepted and provable world, we can determine that the phenomenon will always be of interest to various government agencies including the most skeptical members of the military.
Every UFO report is dealing with a factor that is largely unknown. But there are more potential applications to the word unknown than the visitation of Earth by extraterrestrial forces. And so even if we were to for a moment ignore the reports of alien contact being made with the government, we can definitively say that they will always be interested to some degree in reports of mysterious objects flying about the sky in ways completely beyond what a terrestrial aircraft was capable of. Even if every single case thus far were to be discredited, refuted, and generally removed of any possibility for paranormal or extraterrestrial origin, the very idea of a craft itself reaching a technical capability beyond current understandings of aviation will not only reach the military, but be treated with a due level of diligence and scrutiny. Or if it is not, it should be.
Take the following scenario into consideration. Orville and Wilbur Wright, in 1903 were the first people in the world to accomplish a task far beyond what anyone had thought possible by flying the first manmade self propelled aircraft at Kitty Hawk. Though it only flew a short distance, the knowledge of utmost importance in the case was known as the “Lift Equation” as well as the craft itself. The two worked with limited resources and even more limited manpower. The world of Newtonian physics the two were working with said there was little room for error given the materials they had at their disposal.
Is it not possible, then, that with even more resources and more minds any single group could in theory create an equally groundbreaking scientific device and improve upon it over the course of several years? Any device which could clandestinely break the known laws of physics would give even a limited force an incredible advantage. And so, if this group were to use their invention in order to further their own military ambitions, we would likely find it a Herculean task to overtake them.
And so the tactically minded military would always have to bear this fact in mind, however unlikely it may seem. In our scenario, though the Wright Brothers would never use their plane for combat purposes, it was only a matter of less than ten years before World War I would see the first combat by planes even before the theory of man made flight was widely accepted as truth in many parts of the world. It had become a weapon long before some had even believed in it.
