A USAF Lockheed YMC-130H Hercules, "74-1683", c/n 4658, outfitted with experimental JATO rockets for Operation Credible Sport, a planned second attempt to rescue American hostages held by Iran, is destroyed when the rockets misfire during a test landing at Wagner Field, Eglin Air Force Base, Florida, United States. All crew members survive, but the rescue operation is deemed excessively risky and is cancelled.
