Peter, the current discussion is all about the WHAT of UFOs. "What was it that I just saw?".... It's all about "image detection and identification." What we never discuss (because it's much harder) is the WHY of UFOs. WHAT makes a little more sense than WHY. I believe discussing the WHAT question is just waste of time (since we already know that SIGHTINGS do exist). The real taboo question is WHY would UFOs visit us from "outer space"? The HOW question is also tough: how can they travel tens of thousands of (earth) years through radiation belts, asteroid belts, all the space garbage around the earth, and do it thousands of times a year or day with minimal detection, and for what purpose?
