The key to the UFO conundrum is to realize that such technologies must be, and are being closely guarded to prevent foreign powers from ascertaining their capabilities, what we call Operational Security. The best way to do this is to completely keep everyone not essential to the mission from even knowing that these weapon systems exist. The aliens have NOT landed. And anyone who says they have probably believes that Rambo's guns never run out of ammunition, or that wearing a certain brand of jeans will make gorgeous women in expensive sports cars lock the brakes to get a better view, or that drinking a certain beverage will refresh you and replenish vital nutrients better than water, or that a brand of athletic shoes can will actually improve your performance, or any of the limitless things that we are conditioned to believe by Hollywood or television or others who wish to prey on our innate xenophobia in order to sell us a product that is completely without value or validity. Find out who is benefitting the most from this widespread UFO hoax.
Entire networks have been devoted to it, the public eats it up and begs for seconds.
Please don't be suckered by people shoveling Alien Bull with both hands. Aliens have not landed. Sit in the lotus position and recite this mantra until you believe it completely.
