As I said in my last post, I don't believe in fairies as such. But suppose you did happen to see - ahem! - a tiny humanoid creature, who're you gonna call? Probably not your local newspaper - not unless you've forgotten what "laughing stock" means. You could google "tiny humanoid creature", but it won't get you to any central registry. In the bad old (pre-internet) days it was even worse. However, any sizeable telephone directory is likely to contain an entry commencing,"UFO" or "Flying saucer". And since ufologists have a penchant for weird stories anyway, they have a tendency to accumulate such accounts over the years.
The following reports, except for the last one, were collected by ufologists. It is important to note, however, that no UFO was present in any of the cases.
