November 18, 1977; Troy, Missouri
9:17 PM Local.  A bright white light moving at a high rate of speed came alongside a small aircraft flying at 13,000 feet between Vichy and Troy, Missouri, and paced the airplane for three minutes. The light then moved away at high speed. The pilot reported that while the light was abreast of his aircraft one of his transponders stopped working. After the UFO pulled away the transponder resumed its normal operation. The object paced the aircraft for 3 to 3.5 NM at a distance of 15 nautical miles and was fairly high above the aircraft. The pilot pressed IDENT and nothing happened. He turned on his other transponder and nothing happened. Then it took off on a 120-130 heading and shot out of my sight. The second transponder recovered, but he could never get the first one to work again. The pilot had no trouble with the other instruments. The pilot did not notify ATC (about) a UFO.
