When the ocean liner Ti­tanic went down in 1912, the lo­ca­tion of its sink­ing was wit­nessed by hun­dreds of sur­vivors watch­ing from lifeboats. Still, it took un­til 1985 for the wreck­age to be lo­cated.

Small fa­tigue cracks in the skin of a Boe­ing 737 were iden­ti­fied as the cause of the cat­a­strophic fail­ure of the fuse­lage of Aloha Air­lines Flight 243 in 1988. The plane was fly­ing at 24,000 feet when sud­denly the fuse­lage tore open and a stew­ardess, who was not buck­led into a seat the way the rest of the crew and 89 pas­sen­gers were, was sucked out of the plane. The cap­tain quickly ar­ranged for an emer­gency land­ing and flew the badly dam­aged plane and its oc­cu­pants to safety.

Af­ter­wards, one pas­sen­ger said she had no­ticed a crack in the fuse­lage as she boarded the plane, but did not re­port it. It may have been that crack that proved to be the struc­tural flaw that led to the fuse­lage be­ing torn open and the con­se­quent rapid de­com­pres­sion, but the ex­act se­quence of events is still de­bated.

As his­tor­i­cal ac­ci­dent cases re­veal, lo­cat­ing an ac­ci­dent scene, re­triev­ing wreck­age, and test­ing hy­pothe­ses can be a long and, un­for­tu­nately, in­con­clu­sive process
