The Ectoplasmic Flying Saucer | Interesting Articles, Links and Other Media: A tall Spirit materialised wearing a mask which covered his whole face leaving only his eyes visible. This figure approached Hyman and taking him by the hand led him to the cabinet. Then in a serious voice he said: "I want to tell you that flying saucers do exist, although your world is sceptical of any reports of such. But I say to you that they will one day be an established fact, and will arrive on your planet before man destroys himself; but the time is not yet ripe."
And, as with many of these types of encounters (including Mothman,etc.) pre-knowledge of events concerning the witness is had by the non-human entities.
(There was another South African contactee: Elizabeth Klarer, who lived on the planet Meton with Space Brother Akon and had a child together.)
