Claims to fame

This incident is Case 12 in Isaac Koi's "Top 100" article, since it was referred to in 99 of the books covered by that article.

 

Isaac Koi’s “ICES” Rating for this sighting = 4,368 (out of a potential score of 14*14*14*14 i.e. 38,416)

(1) “Impact” Rating of 14 (out of a potential score of 14), because it is Case 95 in Isaac Koi's "Top 100" article.

(2) “Credibility” Rating of 3 (out of a potential score of 14) because many researchers have put forward compelling evidence that this incident was merely a hoax.

(2) “Expert” Rating of 8 (out of a potential score of 14). It is given this slightly above neutral rating because (at the time of writing) it has included in one of the short lists of the best cases produced by various UFO researchers that have been compiled by Isaac Koi (see the “Best UFO Cases" article at PART 3: Existing lists by various individuals).

(4)“Strangeness” Rating of 13 (out of a potential score of 14). The sighting has a very strangeness rating since the witness accounts, if not hoaxed, would be very difficult to reconcile with a mundane explanation.
