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.

Ground Radar and Air Visuals
July 25, 1952

Osceola, Wisconsin

Dan Wilson:
July 25, 1952, Osceola, Wisconsin (BB)
Numerous unidentified objects were picked up on radar by the 674th AC&W Squadron in the morning. Speeds varied on the radar scope between 14,400 knots and 20,000 knots. There was correlation between these electronic sightings and visual sightings made by pilots of the 109th Fighter Squadron from Minneapolis, Minnesota.

Brad Sparks:
This seems to be electronic interference.  There were  reports/osceola_radar.htm radarscope photos  published way back in 1976 by Brad Steiger in his Project Bue Book book. At 20,000 mph you have only 3 blips covering 200 miles on the 15-second sweep rate of the CPS-6, which is not enough to be sure it's a single object (three random stationary blips popping up can be connected up in the mind of a radar operator).  Visual confirmation by flashes of light for a few seconds is pretty weak.
