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.

Oct. 18, 1951; 140 miles from Tsingtao, China over Yellow Sea (BBU)
At 3:33 a.m. local time a waist gunner aboard a PBY Mariner, RD-5, US Navy patrol plane sighted an unidentified light on the port side of aircraft and notified Ensign George Gregory, the Patrol Plane Commander. The radar man confirmed the contact reporting the distance at 12 miles. The craft was at an estimated 4000 feet altitude. The hull was very large estimated to be 60 feet long. The wings were swept back and down with a dihedral at the tips. The PBY made a turn to place the object between the moon and the PBY. The craft turned also and pulled ahead to twelve miles. The PBY applied power and closed to about 3 to 4 miles. During this time the craft was observed with binoculars. All hands on board observed the hull shape. The craft accelerated slowly to 16 miles where it again was confirmed by radar. It then rapidly pulled away to 22 miles and all contact was lost. The total length of observation was approximately 22 minutes.
