    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.

    Claims to fame

    This incident is Case 4 in Isaac Koi's "Top 100" article, since it was referred to in 228 of the books covered by that article.

    As part of a survey by the Fortean Times in 2007 of various researchers of the ten cases from 1947 onwards that interested them the most, British ufologists Dave Clarke and Andy Roberts indicated that they considered this incident the “most over-hyped UFO case”.

    In an interview in 1998, Kevin Randle said that Roswell was his "favourite" case.

    This incident has also featured in lists by various UFO researchers of the top UFO cases, including the following:

    * a list of cases produced by Stanton Friedman as part of a survey by the Fortean Times in 2007 of various researchers of the ten cases from 1947 onwards that interested them the most.

    * 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 of Dennis Balthaser’s “ten favourite cases” in an article in the MUFON Journal in 2003.

    * a list by James Carrion, the International Director of the Mutual UFO Network, of the “top 10 cases” in an interview in 2006.

     

    Isaac Koi’s “ICES” Rating for this sighting = 23,716 (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 11 (out of a potential score of 14). As with the Strangeness Rating below, it is difficult to assign "the Roswell incident" a single Credibility Rating since the relevant "incident" is actually comprised of many different eye-witness accounts and claims which are of varying degrees of credibility.   The rating assigned here is an attempt to reflect these varying degrees of credibility.

    (2) “Expert” Rating of 14 (out of a potential score of 14). It is given this top rating because 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 11 (out of a potential score of 14). As with the Credibility Rating above, it is difficult to assign "the Roswell incident" a single Strangeness Rating since the relevant "incident" is actually comprised of many different eye-witness accounts and claims which are of varying degrees of strangeness. Some claims merely describe the material found (in varying terms), others claim to have seen alien bodies. The rating assigned here is an attempt to reflect these varying degrees of strangeness.
