Every air passenger owes a dubious debt to a Pan Am flight that plunged into the ocean off Puerto Rico in 1952 – an accident that killed 52 and led to requirements for the passenger safety briefings given on every commercial flight today.
The plane, the Clipper Endeavor, made a hard landing after losing engine power shortly after takeoff. The 17 passengers and crew who survived told investigators everyone lived through the landing, but panic set in as many passengers struggled to find life vests and the crew had a hard time pulling out life rafts.
Within minutes, the plane sank. Explorers found the wreckage of the DC-4 last month by using an autonomous sonar drone to locate the fuselage and tail in 2,000 feet of water.
Now before takeoff, flight attendants instruct passengers about exit locations and where life vests are located and how to inflate them.
“This one became a catalyst, and it helped drive safety steps forward of better flotation equipment and the preflight briefings,” said aviation safety expert John Cox, a pilot and founder of Safety Operating Systems. “So, this is one steppingstone along the path to what we today enjoy as aviation safety. It was a rallying cry at the time.”
And now the recent discovery of this wreck could offer new hope for families who lost loved ones in other ocean crashes like Malaysia Airlines Flight 370 that disappeared 12 years ago with 269 people aboard.
Years of research helped locate the wreckage
This crash first caught the attention of Russ Matthews in 2019 when he saw a blurb about a luggage tag from the flight washing ashore in Florida. He said the historical significance of the Clipper Endeavor prompted him to dig deeper.
That led to years of digging through the Pan Am Airlines and Coast Guard archives looking for clues about the location of the plane’s watery grave. Reports from the Civil Aeronautics Board, which was the predecessor to the Federal Aviation Administration, also helped.
But the key to finding the wreckage was found in records in Puerto Rico from a hearing that was held on the crash, and a map estimating the location of the crash that was done by Air Force pilots who witnessed the crash because they just happened to be in the area on a training flight.
Bad weather disrupted a previous attempt to locate the wreck in 2024 with a towed sonar array that was also documented by the Discovery Channel’s “Expedition Unknown” show. But Matthews said he and the volunteers who work with his Air/Sea Heritage Foundation dreamed of making a second attempt to find it before next year’s 75th anniversary of the crash with one of these newer advanced drones that were originally developed for military uses like finding undersea mines.
Based on the research conducted, the drone actually found the wreckage on its first pass over that area, although the explorers didn’t know that until it returned to the surface with its images.
Discovery Channel documentary
The Discovery Channel’s Josh Gates and his crew were again along for this latest search to capture the moment the plane showed up on images from the drone after they were downloaded. The search will be featured in a special episode of the show this fall.
“To have a front-row seat to an expedition like this as it’s unfolding is tremendous, and so I feel really lucky that we were able to be a part of it,” Gates said.
