Discovery Channel announced Tuesday that a veteran aviation search team has located the wreckage of Pan Am’s Clipper Endeavor, a passenger plane that crashed into the Atlantic Ocean 74 years ago. The intact wreckage was found on the ocean floor off Puerto Rico.
The announcement, shared exclusively with TODAY, solves a long-standing aviation mystery. On April 11, 1952, Pan Am Flight 526A took off from San Juan, Puerto Rico, bound for New York with 64 passengers and 5 crew members aboard. The aircraft crashed shortly after takeoff due to engine issues. Everyone survived the initial impact, but the plane sank within minutes.
52 people drowned, 17 survived, as panicked passengers reportedly remained aboard instead of using available life rafts. U.S. Coast Guard and Air Force rescuers saved the 17 survivors and recovered additional bodies.
The plane was lost for seven decades until the recent expedition. The team used advanced sonar and remotely operated vehicles to confirm the site without disturbing the wreckage, preserving it as a historical site. Discovery Channel plans to air footage and analysis in upcoming specials.
Pan Am’s Clipper operations in the early 1950s relied on such aircraft for transoceanic routes. The loss contributed to the era’s record of incidents before modern radar and safety standards, leading to improved passenger briefings for over-water flights. Families of those aboard have awaited closure for decades.
Aviation historians called the discovery significant for understanding mid-20th-century commercial flight risks. The intact condition could yield new insights into materials, design, and environmental factors. No immediate recovery plans were announced. Authorities will coordinate with maritime archaeologists and descendants on next steps. The site lies in waters with other historic searches.
Discovery Channel positioned the find as part of its commitment to uncovering lost history. Further analysis of the wreckage data is expected in the coming months.
