Wreckage of Pan Am plane that shaped aviation safety found 74 years on

What the report says

BBC World News reported that the wreckage of Pan American Airways’ Clipper Endeavor has been located in the Atlantic Ocean 74 years after the aircraft crashed off Puerto Rico, a disaster linked to major changes in airline safety procedures. The Douglas DC-4 went down on 11 April 1952 soon after take-off following multiple engine failure, according to the report.

The aircraft was carrying 64 passengers and five crew to New York. BBC reported that all 69 people survived the initial water landing, but the plane sank quickly and many passengers were unable to find or use life vests and rafts; 17 people survived and 52 died. The crash became an important reference point for modern safety rules, including required passenger briefings before commercial flights on exits, flotation equipment and how to use life vests.

The search was led by the Air/Sea Heritage Foundation with the Discovery Channel programme Expedition Unknown and other partners. Researchers narrowed the search area using historical records, weather information and documents from a public hearing in Puerto Rico, including a map from air force pilots who had seen the crash. After a weather-hit attempt in 2024, an autonomous sonar drone found the wreckage about 2,000ft below the surface on 2 June, and a later photographic survey confirmed the aircraft’s identity by showing the Pan Am logo and plane name.

BBC said the discovery will feature in an Expedition Unknown special this autumn. More broadly, the find highlights how past accidents shaped routine passenger safety practices that remain part of commercial flying today.
