Paranormal Adept
The Boainai (Papua New Guinea) Father Gill case has always puzzled me.
The Ruwa (Zimbabwe) close encounter is very interesting too.
In both cases, plenty of witnesses but no physical evidence.
The Voronezh case is enigmatic, though the details of the story are very murky.
Like in Zimbabwe, it's kiddie testimony--not necessarily bad, but...
Dechmont woods (Scotland) Robert Taylor close encounter (though it has only one witness, the corroborating evidence found on the spot is quite convincing)
Yep, the reverse of the above cases. Seems we never get the best of both kinds of evidence.
