Flight 19, a group of TBF Avengers, disappears in the Bermuda Triangle.

Flight 19 was the designation of a group of five General Motors 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 flying boat that subsequently launched from Naval Air Station Banana River to search for Flight 19.

The Bermuda Triangle, also known as the Devil's Triangle, is a loosely defined region in the North Atlantic Ocean, roughly bounded by Florida, Bermuda, and Puerto Rico. Since the mid-20th century, it has been the focus of an urban legend suggesting that many aircraft, ships, and people have disappeared there under mysterious circumstances. However, extensive investigations by reputable sources, including the U.S. government and scientific organizations, have found no evidence of unusual activity, attributing reported incidents to natural phenomena, human error, and misinterpretation.
