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.

Radar Incident Cover-Up At Air Base
August 1947
Holloman Army Air Field, New Mexico

Brad Sparks:
Late Aug. 1947?. Alamogordo [Holloman] Army Air Field, New Mexico (BBU)
Time not given. AMC Watson Labs Project MOGUL engineer P. Rosmovski tracked a stationary target at 200 miles altitude using a modified CPS-4 height-finder radar aimed at 70 elevation. [Normally  CPS-4 requires a crew of 6 operators so there may have been other witnesses.] (Sign Microfilm Roll 2, pp. 363, 367-8; FOIA; Loren Gross Aug-Dec 1947 SUPP p. 28; Project 1947) 2+ radar

Fran Ridge:
The radar is modified to track objects at very high altitude. They aim the antenna straight up and pick up a target at 200 miles up. The report leaks out, Project SIGN sends two high-level investigators, but the prime witnesses are conveniently not available. For the full report documents, see links below. Not found in the original Project Blue Book unknowns, this incident IS listed in the updated list by Brad Sparks.

Brad Sparks:
......the CPS-4 radar had been specially "modified" for the specific purpose of extending its 90-mile range to some 250 miles and to point it straight up into outer space to look for targets -- and then it did exactly what it was specially designed to do.
