Pan Am Clipper Endeavor wreckage found 74 years after 1952 crash

The wreckage of the Pan American World Airways (Pan Am) Clipper Endeavor, which crashed into the Atlantic Ocean in 1952, has been discovered off the coast of Puerto Rico. The exact location of the aircraft remained unknown for over seven decades.

The Douglas DC-4 aircraft departed from San Juan for New York on April 11, 1952. Shortly after takeoff, it lost power to two engines, forcing an emergency landing on the ocean surface. While all 64 passengers and five crew members initially survived the crash, the plane sank within minutes. Only 17 people were rescued; 52 perished.

The tragedy had a significant impact at the time, as Pan Am was considered a symbol of the golden age of international travel. The accident also profoundly influenced future civil aviation safety standards. Investigations revealed that many passengers struggled to find and properly use their life vests during the evacuation. This led to the subsequent introduction of mandatory pre-flight safety instructions, now a standard part of commercial flights worldwide.

The wreckage was found on June 2 by a team from the Air/Sea Heritage Foundation, Deep Sea Vision, and the Expedition Unknown program. Using an autonomous underwater vehicle equipped with high-performance sonar, they located the aircraft's fuselage at a depth of approximately 600 meters. Researchers report that the Pan Am logo and the name "Clipper Endeavor" are still recognizable on the debris.
