USAF B-36 radar operator Major Paul E. Gerhart and navigator Major Charles J. Cheever on a flight from Goose Bay, Labrador, to Resolute, North West Territories, heading northwest at 208 knots (239 mph) over Hudson Strait, picked up radar interference which came from an unidentified aircraft at relative bearing 130° (E) at 28 nautical miles. (32 miles) heading away. Anti-jamming device on the APQ-24 radar was turned on at 11:20 p.m. but did not affect the jamming on the radar scope. At 11:35 jamming covered 120° of the right side of the radar scope and then an unidentified aircraft was seen visually on the right side of the B-36, which was then at 18,000 feet at 65°40' north, 71°40' west (over southwest Baffin Island). Object had "unconventional running lights" all white instead of red-green, with twin white flashing tail lights, traveling about 30 knots faster than the B-36, crossed the front from right to left heading 334° true towards the NNW, and was in view about 20 minutes (to a distance of about 12 miles). While the object was still visible, at 11:50 p.m. the B-36 autopilot and APQ-24 radar set went out, the latter returning after a few minutes about when the object disappeared. ECM operators Staff Sergeant Donald E. Jenkins and Staff Sergeant Doty T. Larimore on two B-36 flights from Goose to Resolute while still over Labrador the next day detected carrier wave signals at several frequencies and some radar like pulses at other frequencies, all below 1,000 MHz.
