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.

Martin Shough:

561200  Far East  Asia  December 1956, A,V: This one appears to be pending and without clear date and details.  Could it be the Dec 17 1956 airborne radar-visual onear Tsushima, between S Korea and Japan?

Dec. 17, 1956; Near Itazuke AFB, Japan
At 3:20 p.m. local time, an object was picked up on airborne radar of an F-86D aircraft at 20 nautical miles. The aircraft had a lock-on at 15 nautical miles on a steady overtake on a course of 270 degrees at 600 to 700 knots. The object and the observing aircraft were heading 270 degrees through the entire chase. A visual contact was made at 8 nautical miles and the F-86 closed to within 5 nautical miles and could not close any further. The object then started to pull away from the F-86 and at 12 nautical miles all indications on radar disappeared. The pilot estimated the speed of the object upon radar disappearance at 1500 to 1800 knots. Observation times were, radar: 7-8 minutes, visual: 3-4 minutes. The object was described as tan in color and round on top. Interference resembling ECM was experienced by both the observing aircraft and wingman. The general area of observation was 34-00N, 131-00E, slightly east of the Japanese island of Tsushima.
