Wreckage found of Pan Am plane crash that helped lead to today's safety briefings on every flight

Wreckage from a Pan Am plane crash that occurred 74 years ago has been discovered off the coast of Puerto Rico. The aircraft, known as the Clipper Endeavor, sank after 52 people perished because they failed to evacuate in time. This tragedy directly led to the implementation of mandatory passenger safety briefings on every flight, including routine instructions on how to locate exits and inflate life vests that are standard in aviation today.
