Wreckage of Pan Am plane found decades after crash that changed aviation safety

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 plane, the Clipper Endeavor, made a hard landing after losing engine power shortly after take-off. 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 more than 600 metres of water.

Now before take-off, 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 stepping stone 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.
