I wish there was a serious investigation into flying saucers that wasn't conducted by crackpots. Unfortunately nearly all of the people who are interested in them kind of manufacture the evidence to fit the theories rather than the other way around. So it's very hard to find any dispassionate treatment of them. Maybe there isn't any scientific basis in which case that's why you never see any scientific evidence.
