The second possibility is that the objects are actually operated by an arm of the U.S. government. Rumors of the federal government studying crashed UFOs or experimenting with secret technology have been rampant for decades, though with scant proof. If these were indeed secret U.S. craft, it is clear why they’re being hidden. The Super Hornet was a top of the line aircraft in 2004 and yet the object easily out-maneuvered and out-accelerated it. If America’s enemies mastered such technology, most (but apparently not all) of our armed forces would be defenseless against them.
