So aside from making lots of money for various "In Search Of" and "Unsolved Mysteries" shows, what progress, if any, have we made on the issue? The usual quote from skeptics is "where's the physical evidence?", but we have many simultaneous sighting and radar contacts on record. True believers insist on a governmental cover-up of massive proportions, which, to put it mildly, seems highly improbable.
Are there some conclusions we can reach? Is sixty years of sightings enough to reach any kind of conclusions at all?"
