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.

Ten Targets With Gnd Radar / No Visuals By Jets
June 3, 1952
Chicago, Illinois

June 3, 1952; Chicago, Illinois (BB)
9:27 a.m. CST. Six to 10 targets were detected on AN/CPS 6B radar of the 755th AC&W Squadron.  These targets were at the GEO. REF. position of DM 3012, on a heading of 310 degrees at an altitude of 25,000 feet at an estimated speed of 450 mph. The controller on duty checked with C.A.A. and M.F.S. for flight plans, but they had no flight plans. These radar targets were then declared unknowns, and an F-86 aircraft was scrambled out of O'Hare Field. The F-86 flying at 29,000 feet was radar directed toward the unknowns and merged with the unknown track. The F-86 was unable to sight any aircraft at the position occupied by the unknown track. At 9: 46 a.m., the unknown track turned to a heading of 140 degrees and  followed the lake shore to position CM 5542. The unknowns then turned to a heading of 90 degrees and maintained this until position DM 3545. Now the unknown turned to a heading of 120 degrees and faded out at 10:16 p.m. The target indication was very strong on the PPI scope. During this incident a total of eight (8) aircraft were scrambled from three (3) different bases but no interception was accomplished.
