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.

F-61 "Black Widow" Radar Case
October 15, 1948
Kyushu/Fukuoka, JAPAN

Richard Hall:
Features: Aerial encounter, radar-visual, cat-and-mouse pursuit. An F-61 "Black Widow" night fighter crew on patrol over Japan picked up a UFO target on radar moving at about 200 m.p.h. The crew made six attempts to close in on the object, and each time it rapidly accelerated to about 1,200 m.p.h. leaving the interceptor behind. Then it would slow down again until the interceptor began closing in once more. On one pass the crew saw the silhouette of an object shaped like a "rifle bullet and apparently 20-30 feet long.

Francis Ridge:
This original report includes the Hynek and McDonald versions, but more recently added reports (May 2005) include the report and analysis by NARCAP and the posting of official documents from the BB Microfilms. This case was listed among the original BB "Unknowns" and is carried in the Comprehensive Catalog of Project Blue Book Unknowns by Brad Sparks:

Oct. 15, 1948.  Fukuoka, Japan.  11:05 p.m.  USAF pilot 1st Lt. Oliver Hemphill Jr. and radar observer 2nd Lt. Barton Halter flying a P-61 “Black Widow” night fighter made 6 interceptions of the same or different objects tracked on airborne radar, only one seen visually.  Dull or dark translucent object shaped like a dirigible with a flat bottom and clipped tail end.  Speed varied from 200 to about 1,500 mph.  Pilot tried to close on visual object, but it dove away fast.  (FOIA;  Jan Aldrich)         2        RV
