An exploration team using an autonomous underwater vehicle located the wreckage of the Pan American Clipper Endeavor on July 22 [1].

The discovery resolves one of the most enduring aviation mysteries in Puerto Rico and provides a chance to study a disaster that influenced global flight safety standards.

The aircraft was found in the Atlantic Ocean off the north coast of Puerto Rico [2]. It rested at a depth of approximately 600 meters [3]. The plane had been missing for 74 years [4], having disappeared after a crash in 1952 [1].

Records indicate there were 69 people on board the flight [1]. The accident resulted in 52 deaths [1]. For decades, the exact location of the debris remained unknown despite the proximity to the coast.

Experts said the find is critical for understanding the factors that led to the crash. The 1952 event is credited with driving significant changes in aviation security and safety protocols [5]. The use of autonomous technology allowed the team to reach the deep-sea floor where the fuselage settled.

The mission aimed to bring closure to the historical record of the disaster [6]. By analyzing the wreckage, researchers hope to gain further insight into the structural failures, or environmental conditions, that contributed to the loss of the Clipper Endeavor.

The recovery of the Clipper Endeavor wreckage demonstrates the increasing efficacy of autonomous underwater vehicles in solving historical cold cases. Beyond the archaeological interest, the site serves as a physical record of the transition into the early jet age and the subsequent evolution of safety regulations that now govern modern commercial aviation.
