Eskin Kuhn was a United States Marine at the Guantanamo Bay military base in Cuba, in 1971. One hot day, with clear visibility, he was taking a break when he saw an amazing sight. He described the experience in his own words.
I saw 2 Pterosaurs (or Pterodactyls . . . what’s in a name?) flying together at low altitude, perhaps 100 feet, very close in range from where I was standing . . . I had a perfectly clear view . . . The rhythm of their large wings was very graceful, slow . . . The Pterosaurs I saw had the short hind legs attached to the rearward-most part of the wing, and they had a long tail trailing behind with a tuft of hair at the end. . . . The head [had] a long crest at the back, long bill, long neck with a crook in it. The chest of the creatures was similarly prominent, protruding forward like the prow of an old ship . . . their wingspan [was] roughly 10 feet.
Guantanamo Bay, Cuba, pterosaurs (quoted below)
The two obvious pterosaurs observed by Eskin Kuhn during his military duty at Guantanamo Bay, Cuba, in 1971, were sketched by him soon after the sighting. I have encountered no contradiction in anything that he has said during the past four decades, nothing to discredit his account . . .
Are Reports of Living Pterosaurs Anecdotes? (quoted below)
That critic labeled the eyewitness report of Eskin Kuhn “an unlikely anecdote.” But the link that he gives in his original posting is to a site with at least twenty-nine short paragraphs about the sighting; that alone makes the word “anecdote” questionable. And all of those paragraphs were quotations of the eyewitness, Eskin Kuhn; that shoots down the word “anecdote.”
