Wreckage of Pan Am plane found 74 years after it crashed off Puerto Rico

The discovery ends a decadeslong search and could help preserve the wreck site as a memorial to the 52 people who died.

  • On June 2, 2026, a multi-partner search team led by the Air/Sea Heritage Foundation, Deep Sea Vision, and Discovery Channel located the wreckage of Pan Am's Clipper Endeavor 2,000 feet below the ocean surface off Puerto Rico.
  • The Clipper Endeavor crashed on April 11, 1952, after losing both right-side engines shortly after takeoff from San Juan, killing 52 people and leaving 17 survivors; the disaster prompted mandatory pre-flight safety briefings industry-wide.
  • Using high-resolution sonar and autonomous underwater vehicles, researchers captured more than 350,000 images of the wreckage without disturbing the site, resolving a 74-year-old aviation mystery.
  • The Air/Sea Heritage Foundation is coordinating with the Government of Puerto Rico to secure legal protections for the wreck site and establish a permanent memorial; no remains will be recovered.
  • Details of the discovery will feature in an upcoming episode of Discovery Channel's Expedition Unknown later this year, potentially offering new hope for families seeking closure regarding other missing ocean aircraft.
