Gorman dogfight incident
On 1 October 1948, Lieutenant George F Gorman of the North Dakota Air National Guard has a “dogfight” with an alleged UFO as he approached Fargo, North Dakota in an F-51.
This incident is Case 33 in Isaac Koi's "Top 100" article, since it was referred to in 64 of the books covered by that article.
Isaac Koi’s “ICES” Rating for this sighting = 5,005 (out of a potential score of 14*14*14*14 i.e. 38,416)
(1) “Impact” Rating of 13 (out of a potential score of 14), because it is Case 33 in Isaac Koi's "Top 100" article.
(2) “Credibility” Rating of 11 (out of a potential score of 14) because the sighting report was made by a military witness and the debate has centered on what was actually there.
(2) “Expert” Rating of 7 (out of a potential score of 14). It is given this neutral rating because (at the time of writing) it has not been included in any 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), but also is not commonly given by UFO researchers as an example of an incident that can be explained by hoax, misperception or other mundane cause.
(4)“Strangeness” Rating of 5 (out of a potential score of 14). The sighting has a relatively low strangeness rating since there several researchers (particularly Donald Menzel) have plausibly suggested that Gorman saw some form of balloon carrying a candle/light.
