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.

May 13, 1967; Colorado Springs, Colorado
At 1640 MDT, at the Colorado Springs airport an object was picked up on radar. During this time a Braniff flight was coming in for a landing on runway 35. The track of the object behaved like a ghost echo, perhaps a ground return being reflected from the Braniff aircraft. The object blip appeared at about twice the range of the Braniff blip. When Braniff touched down, however, the situation changed radically. The UFO blip pulled to the right (east) and passed over the airport at an indicated height of about 200 ft. The object track passed within 1.5 miles of the control tower. The object was not visible even through binoculars by personnel in the control tower. This case was written up in the SCIENTIFIC STUDY OF UNIDENTIFIED FLYING OBJECTS, conducted by the University of Colorado, and it was stated there: This must remain as one of the most puzzling radar cases on record, and no conclusion is possible at this time. It seems inconceivable that an anomalous propagation echo would behave in the manner described, particularly with respect to the reported altitude changes, even if AP had been likely at the time. In view of the meteorological situation, it would seem that AP was rather unlikely. Besides, what is the probability that an AP return would appear only once, and at that time appear to execute a perfect practice ILS approach?
