Researchers have found the wreckage from a Pan Am flight that plunged into the ocean off Puerto Rico in 1952. The accident killed 52 people and led to requirements for the passenger safety briefings given on every commercial flight. It changed aviation forever.
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. Unfortunately, most passengers panicked and struggled to find life vests. Additionally, the crew had a hard time pulling out life rafts.
The cabin crew tried to calm the 64 passengers, but 52 of them stayed pinned to their seats and wouldn’t move. Within minutes, the plane sank to the sea bottom 2,000 feet below.
“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, where life vests are located, and how to inflate them.
Russ Matthews became fascinated with the idea of finding the plane in 2019 and found the approximate location in Puerto Rican records.
They attempted to find it in 2024, but unfavorable weather conditions ended the search.
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.
Discovery Channel’s Josh Gates was with the crew and filmed for the Discovery Channel. It will be shown this fall.
They have been in contact with some of the families impacted by the crash, including the accident’s only two known living survivors.
