Searchers have discovered the wreckage of Pan Am's Clipper Endeavor, 74 years after the aircraft crashed into the ocean off Puerto Rico in 1952, according to CBS News and the Associated Press.
The New York-bound DC-4 lost engine power shortly after takeoff, killing 52 people. Survivors later told investigators that panic and confusion over life vests and rafts contributed to the high death toll.
Using years of historical research and an autonomous sonar drone, the expedition located the fuselage and tail section nearly 2,000 feet below the surface. According to the report, archived crash records, witness accounts and weather data helped narrow the search area.
The expedition team is now working with Puerto Rican authorities to protect the wreck site and has contacted families of victims, including the crash's only two known living survivors.
