WherePalgongsan (Daegu) to Yeongil Bay (Pohang), South Korea

During the Team Spirit exercise on the night of 31 March 1980 two South Korean F-4 Phantoms were sent toward a bright light near Daegu. It jumped to Yeongil Bay and stopped, and the jets circled it: an oval as big as an airliner, ringed with lights and shooting out golden or welding-blue flames. Neither aircraft nor ground radar saw it. Both senior pilots, one later a major general, told the story on the record; it left over the East Sea.

A bright 'star' jumped 'instantly' toward Yeongil Bay and stopped dead; he closed to about 1,000 ft and circled an airliner-sized oval, flat on top, covered in coloured lights, with golden flashes 'like molten metal in a furnace' from its centre.
