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.

Unidentified Target Tracked / F-80 Intercepts
April 28,1950
Wakkanai, Japan

Brad Sparks:
April 28, 1950; About 2 miles W of Wakkanai, Japan (BBU)
11:30 a.m., 12:30 p.m. Misawa AFB 9th Fighter Bomber Sq USAF pilot 1st Lt. James H. Harvey flew an F-80C jet to attempt to intercept unidentified target tracked by Radar Site #18 without success. After 1 hr, at 12:30 p.m., while flying due N 360° about 2 miles W of Wakkanai at 300 mph (IAS?) at 30,000 ft Harvey saw an object about 7 miles to his left in the W on a S 180° heading at 600-650 mph and lost it in the clouds or over the top of the clouds after about 5 secs. Object apparently circled around at high speed in about 10 secs [roughly 8 miles or about 3,000 mph] reappearing on Harvey's right [at around 2 o'clock position] and continued to circle from right to left in front of the F-80C apparently still at 10,000 ft and closer [roughly 1 mile], was seen 'clearly' contrasted against the ocean. Object was a white square 12 x 12 ft (height x length) thin, appearing somewhat like an aerial tow target, oriented vertically, with no evidence of propulsion, exhaust, control surfaces or lights. Object was lost after about 5 secs when it blended in with the lower overcast clouds on about 270° W heading [roughly 10 o'clock from F-80C possibly 3 miles range]. F-80C had been in continuous radio contact with Radar Site #18 during UFO sightings but radar was unable to track either the UFO or the F-80C. Harvey had another F-80 in sight the entire time. Harvey descended to 18,000 ft and searched for the UFO for 15 mins without success. Similar incident previous day near Camp Haugen, Japan. (Jan Aldrich)
