Wreckage from a 1952 Pan Am flight crash off Puerto Rico, which killed 52 people and influenced airline safety reforms, was discovered using an autonomous underwater drone. The search, led by the Air/Sea Heritage Foundation and Deep Sea Vision, utilized historical records and advanced sonar technology to locate the DC-4 aircraft in nearly 2,000 feet of water.
