Discovery opens new chapter in aviation safety history

The wreckage was located last month by a team from the Air/Sea Heritage Foundation in collaboration with Discovery Channel’s “Expedition Unknown,” hosted by Josh Gates. The expedition located the aircraft’s fuselage and tail sitting on the seafloor at a depth of roughly 2,000 feet off the coast of Puerto Rico.

The Clipper Endeavor, a Pan Am DC-4, crashed on Good Friday in April 1952. Twelve passengers and five crew members survived the plane’s hard landing on the water, but the aircraft began sinking rapidly. The Associated Press reported that survivors struggled to find life vests, were reluctant to leap into the waves, and the crew struggled to deploy the rafts. The plane sank within minutes, taking 52 people down.

Aviation safety expert John Cox said the disaster became a crucial turning point for airline safety practices.

“This one became a catalyst, and it helped drive safety steps forward of better flotation equipment and the preflight briefings,” Cox told the Associated Press. “So this one steppingstone along the path to what we today enjoy as aviation safety. It was a rallying cry at the time.”

The reforms that followed the Clipper Endeavor crash include the preflight safety demonstrations that flight attendants deliver on every commercial flight today, along with improvements to life-vest storage and emergency-raft deployment systems that the expert described as key steps in aviation safety.
