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.

Target Follows Sweep
Early May 1952
NAS, Willow Grove, PA

Fran Ridge:
This interesting case came from Jan Aldrich and is one of the files from Project Interloper. Ground Control Approach radar picked up a target in bad weather conditions near the center of the scope. By the next sweep (32 rpm) the target had moved almost five miles, indicating the object was moving approximately 3,600 mph. It was seen to move as the trace swept past it. (A similar evnt occurred at Washinton National in July where the target "blossomed" on the scope.) By the fourth sweep the target had moved off to the ten mile limit of the GCA scope. Target was visible on two radar scopes, operating on two different fequencies, so this was no malfunction. Object was tracked the next day under similar weather conditions.
