Yep. The next alarmist scare du jour. Are you ready to be terrified once again? Or have you had enough bullsh*t?
Amazing isn't it that advanced alien technology somehow got here, and our Air Force is able to shoot them down easily?
FYI, we now know enough about the history of the Universe to be certain that there are no advanced species beyond us in the Universe. How do we Know? Because we can be reasonably certain that our Sun is the oldest star capable of creating Earthlike planets. The chance of their being an older one is vanishingly small. ET is probably not even green slime yet.
So what is the military spending money on studying UFOs when they certainly know this? That is what you should be concerned about.
