Brief comments to be added on this group.
As noted in Part 3 of Isaac Koi’s “Best UFO Cases” article (i.e. in the Part entitled Existing lists by various individuals), Jacques Vallee’s book “Challenge to Science : The UFO Enigma” (1966) included a list of 5 cases nominated by NICAP as being the best (see Footnote 3.12). Those cases were:
(1) Nash and Fortenberry (Case 44 in Isaac Koi's “Top 100” article),
(2) Red Bluff (Case 93 in Isaac Koi's “Top 100” article),
(3) Captain Sperry,
(4) Southwest, 1957,
(5) Socorro (Case 5 in Isaac Koi's “Top 100” article).
