RADCAT is a revitalized special project now being conducted jointly by NICAP & Project 1947 with the help and cooperation of the original compiler of RADCAT, Martin Shough, to create a comprehensive listing of radar cases with detailed documentation from all previous catalogues, including UFOCAT and original RADCAT.

Radar/Visual At Air Force Radar Site
Sept. 1, 1952
Yaak, Montana

Brad Sparks:
Sept. 1, 1952; Yaak, Montana (BBU 2023)
4:45 a.m. Visual sighting by 2 USAF enlisted men, radar tracking by 3 men using FPS-3 radar set. 2 small, varicolored lights became black silhouettes [of "dark, cigar-shaped object"?] at dawn, flew erratically. 1 hours. (Berliner; cf. Ruppelt p. 194)

Loren Gross:
A newsman from Oleans, New York, a Mr. Bob Barry, interviewed a S/Sgt. William Kelly who was stationed at the Yaak radar installation in 1953. According to Sgt. Kelly, on one occasion UFOs appeared on the site's radar screens exhibiting changes of direction as many as five times a minute. Some course changes w«re 90 degrees and speeds were measured as high as 1,500 mph. Six blips at one time appeared on the radar scopes and the strange targets came within 10 miles of the GCI site. So close was the indicated range the radar personel left their windowless operations room to check the sky with the naked eye. Sure enough, six objects could be seen in the sky an estimated 10 miles away. When first spotted, the six UFOs were in an in-trail formation, and shortly thereafter the six UFOs changed to an in-line abreast grouping. Finally, the UFOs switched to a vertical stack. Sgt. Kelly said he remembers tracking the UFOs on the radar executing vertical climbs that exceeded the limit of the site's height finding equipment (This was probably 100,000 feet). 19. (UFOs: A History, 1953: Aug-Dec.,  Pg.5; 19. Hall, UFO Evidence, Pg. 85)

Mike Swords:
Ruppelt was very high on this case as it is listed as one of the prime cases brought before and discussed by the Robertson panel (*). James McDonald also has file on it. (Ruppelt probably mis-remembered and put it (book) one month early [it is September 1, instead of August 1).
