搜救团队成功定位了泛美航空公司Clipper Endeavor号飞机的残骸，该飞机于1952年4月11日在波多黎各附近大西洋坠毁[2]。残骸位于海下2000英尺处[1][2]，由Air/Sea Heritage Foundation与Discovery Channel合作，于2025年6月2日通过声纳无人机发现[2]。
这场空难共造成52人丧生[1]，机上69人中仅17人生还[2]。飞机失去动力后进行了硬着陆，并在几分钟内沉没[1]。幸存者在离开飞机时陷入混乱[1]。
该空难成为航空安全史上的转折点。这次事故促使航空业建立了强制性乘客安全简报制度[1][2]，并促成了更好的浮力设备规定[2]。节目主持人Josh Gates表示："每当你今天登上飞机时，你都因为74年前发生在Clipper Endeavor号及其乘客身上的事故而更加安全"[2]。
搜救工作历时多年。关键线索来自波多黎各的听证会记录和空军飞行员绘制的地图[1]。2024年的搜索因恶劣天气被迫中止，团队在75周年纪念前回归并在无人机的首次搜索通过中成功发现了残骸[2]。这一发现将在Discovery频道《Expedition Unknown》节目中播出专集[1]。
Search teams have located the wreckage of the Pan American Airways Clipper Endeavor, which crashed in the Atlantic Ocean near Puerto Rico on April 11, 1952 [2]. The discovery was made on June 2 using autonomous sonar drones that detected the aircraft at a depth of 2,000 feet [2].
The disaster claimed the lives of 52 people [1], though sources differ on the total number aboard: one reports 69 people with 17 survivors [2], while another indicates 17 passengers and crew members survived after the aircraft lost power, made a hard landing, and sank within minutes [1]. The wreckage, including the tail section, was identified during the search team's first pass through the search area [1].
The crash proved pivotal in aviation history, prompting the industry to establish mandatory preflight safety briefings for all commercial flights [1][2]. The accident also led to improved requirements for flotation equipment [2].
The recovery effort required years of investigation, drawing on clues from Puerto Rican hearing records and maps created by Air Force pilots [1]. After preliminary searches in 2024 were halted due to severe weather, the Air/Sea Heritage Foundation and Discovery Channel team returned and succeeded in locating the wreckage ahead of the disaster's 75th anniversary [2].
Josh Gates, host of the Discovery Channel's "Expedition Unknown," reflected on the discovery's significance: "Every time you step onboard an airplane today, you are safer because of what happened to Clipper Endeavor and her passengers three-quarters of a century ago" [2]. The findings will be featured in a special episode of the program [1].
