The wreckage of a New York City-bound Pan Am flight, the "Clipper Endeavor," has been located more than 74 years after it crashed off Puerto Rico, killing 52 people and prompting significant changes to air safety protocols. The discovery was made in June by a search team after a seven-year investigation led by the Air/Sea Heritage Foundation, in partnership with the Discovery Channel.
"Seeing the bright aluminum fuselage shining back at us from the ocean floor was a hugely emotional moment," said Josh Gates, host of the show "Expedition Unknown," which was involved in the search. The largely intact remains of the Douglas DC-4 aircraft were found approximately 2,000 feet below the surface of the Atlantic Ocean.
The plane, which was roughly the size of a modern Boeing 737, broke into two sections on the ocean floor, with its Pan Am logo still visible. The recovery team utilized advanced sonar technology and autonomous underwater vehicles to locate the aircraft.
The crash occurred on April 11, 1952, shortly after the plane took off from San Juan for New York City. The aircraft experienced multiple engine failures just 10 minutes into the flight. While all 64 passengers and five crew members survived the initial impact, the plane began taking on water in rough seas. Despite the availability of flotation devices and established protocols for their use, 52 people perished as the plane sank within three minutes. There were 17 survivors, aided by rescue efforts from the U.S. Coast Guard and Air Force.
Prior to this incident, pre-flight safety briefings for passengers were not standard practice. The tragedy of the "Clipper Endeavor" highlighted the critical need for such procedures, leading to mandatory safety demonstrations regarding exit locations and the use of flotation devices. These changes have since become a cornerstone of modern air travel safety.
"There was no demonstration of where the exits were, where the flotation devices are. And so in all of that chaos and all that panic, 52 people drowned in and around this plane," Gates stated, emphasizing the impact of the lack of safety information. "Every time you step onboard an airplane today, you are safer because of what happened to Clipper Endeavor and her passengers three quarters of a century ago."
The Air/Sea Heritage Foundation began its search for the "Clipper Endeavor" in 2019. The foundation partnered with Deep Sea Vision, an Eco Minerals company, to employ their advanced underwater vehicles in the extensive search effort. Discovery Channel plans to feature the finding in an upcoming episode of "Expedition Unknown."
