It’s been an interesting week for aliens. First we have Oxford University citing research that suggests we are probably alone in the universe. We don’t like that idea. Usually when I’m doing a presentation, I invite questions. One that always shows up is whether I believe in UFO’s? My usual response is no. Bring one down onto my driveway, let me kick the tires, and I’ll let you know. The disappointment in the audience is clear. But I suspect FTL travel is not possible. If that’s true, visitors would have need years, or maybe centuries, to get here from nearby stars. If they invested that much time, why would they simply ride around near Phoenix and scare the devil out of a couple of pilots?
