Flight 19 was the designation of five TBM Avenger torpedo bombers that disappeared over the Bermuda Triangle on December 5, 1945 during a United States Navy overwater navigation training flight from Naval Air Station Fort Lauderdale, Florida. All 14 airmen on the flight were lost, as were all 13 crew members of a PBM Mariner flying boat assumed by professional investigators to have exploded in mid-air while searching for the flight.
