The Tremonton, Utah incident occurred on 2 July 1952, involving film taken during a sighting by US Navy Warrant Officer Delbert C Newhouse.
Commonly referred to as “the Tremonton film” and “the
This incident is Case 34 in Isaac Koi's "Top 100" article, since it was referred to in 64 of the books covered by that article.
The Tremonton film was one of two motion pictures of UFO sightings considered by the Robertson Panel, organized by the CIA, in January 1953.
Isaac Koi’s “ICES” Rating for this sighting = 5,460 (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 34 in Isaac Koi's "Top 100" article.
(2) “Credibility” Rating of 12 (out of a potential score of 14) because the debate regarding this incident has centered on what was filmed, rather than whether the incident was a hoax.
(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 below average strangeness rating since there is relatively limited evidence to be explained as to the nature of the objects that was filmed. Several researchers have plausibly suggested that the objects that were filmed were merely birds.
