The Trindade Island photographs have been referred to as “the most famous of all purported photographs of a UFO” (by Donald Menzel and Lyle Boyd in their book “The World of Flying Saucers”, 1963).
This incident is Case 26 in Isaac Koi's "Top 100" article, since it was referred to in 72 of the books covered by that article.
This incident came third in a survey in 1965 by Jacques Vallee of the opinion of various UFO groups as to the most significant UFO sightings. This case featured in a list of 5 cases which APRO nominated as being the best in the same survey.
The Trindade Island photographs were the only photos to get their own chapter 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 been included within various lists of the best UFO cases produced by various researchers. For example:
- a list by Bruce Maccabee of 20 cases which give “the best evidence for an extraterrestrial origin for the UFO phenomenon”.
- a list by Ronald Story of the 4 best photographic cases.
