Wreckage of Pan Am plane found in ocean 74 years after deadly crash

Searchers have found the wreckage from 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.

The New York-bound 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.

According to the Pan Am Historical Foundation, the cabin crew tried to calm the 64 passengers.

"Although the Clipper was equipped with life rafts and personal floatation for all aboard, most of the passengers remained glued to their seats, more afraid of facing the reality of their situation than the momentary mirage of safety offered by remaining in the plane's cabin," the foundation said. "It would prove a fatal mistake for 52 of them."

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.

"This accident changed aviation forever," the Discovery Channel's Josh Gates said in a social media video announcing the discovery. "It led to sweeping changes, including the introduction of the now mandatory safety briefing every time you fly."

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 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.

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.
