Flight 19 was the designation of a group of five Grumman TBF Avenger torpedo bombers that disappeared over the Bermuda Triangle on December 5, 1945, after losing contact during a United States Navy overwater navigation training flight from Naval Air Station Fort Lauderdale, Florida. All 14 naval aviators on the flight were lost, as were all 13 crew members of a Martin PBM Mariner that subsequently launched from Naval Air Station Banana River to search for Flight 19.
