Washington National sightings
Several radar/visual sightings occur near Washington DC during July 1952 and receive considerable publicity.
(Commonly referred to as the Washington National sightings).
This incident is Case 8 in Isaac Koi's "Top 100" article, since it was referred to in 171of the books covered by that article.
Official US documents about this incident can be found online. See the material on the ambitious “Project Blue Book Archive” website in relation to Project Blue Book Case Number 1649 and Project Blue Book Case Number 1661, which commences at the links provided (and continues on the pages which follow them).
This incident came second in a survey in 1965 by Jacques Vallee of the opinion of various UFO groups as to the most significant UFO sightings.
This incident came seventh in an online poll conducted in March/April 2006 by Paul Kimball of “the UFO case with the ‘best evidence’ ever”. This incident has also featured in a list by Paul Kimball of his own nominations for the top 10 cases.
This incident also featured in a document (“the Rockefeller Briefing Document”) endorsed by Dr Mark Rodeghier (President of CUFOS), Richard Hall (Chairman of FUFOR) and Walter Andrus (President of MUFON) as containing “the best available evidence for the existence of UFOs”.
This incident has also featured in lists by various UFO researchers of the top UFO cases, including the following:
* a list by Don Berliner of “the top 10 cases of World Ufology” in an interview made available on the UFO UpDates discussion List on 14 January 2007.
* a list by James Carrion, the International Director of the Mutual UFO Network, of the “top 10 cases” in an interview in 2006.
* a list of Dennis Balthaser’s “ten favourite cases” in an article in the MUFON Journal in 2003.
Isaac Koi’s “ICES” Rating for this sighting = 25,480 (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 8 in Isaac Koi's "Top 100" article.
(2) “Credibility” Rating of 14 (out of a potential score of 14) because radar operators saw something on their screens. The debate has centered on what (if anything) was actually detected by the radar systems.
(2) “Expert” Rating of 13 (out of a potential score of 14). It is given this relatively high rating because (at the time of writing) it has been included in many 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 10 (out of a potential score of 14). The sighting has an above average strangeness rating since there is considerable debate as to whether the reported radar returns are explainable by temperature inversions or other mundane causes.
