The Costa Concordia sank on January 13, 2012, primarily due to human error and a "judgment lapse" by Captain Francesco Schettino. The ship deviated from its planned, computer-monitored course to perform a "sail-by salute" (an unofficial greeting) to the island of Isola del Giglio. During this maneuver, the ship struck an underwater rock formation that tore a 35-meter (115 ft) gash in its port side. This breach flooded the engine room and generators, causing a total power blackout. The disaster was exacerbated by a delayed evacuation order; the Captain waited over an hour to sound the alarm, during which the ship listed too heavily to launch many lifeboats. In 2026, maritime law students study this case as a warning against "normalization of deviance"—where safety protocols are ignored for tradition or ego—leading to the tragic loss of 32 lives.
