The SS Andrea Doria, a luxurious Italian passenger liner, was on a voyage from Genoa to New York City when it collided with the MS Stockholm, a Swedish freighter, in thick fog. The collision occurred in the early morning hours off the coast of Nantucket Island, and the impact was devastating. The Stockholm struck the Andrea Doria on its starboard side, causing severe damage and a significant listing angle. As the crew and passengers scrambled for safety, lifeboats were lowered, and emergency signals were sent out, prompting nearby ships to respond to the crisis. Many passengers were rescued, but the chaotic conditions contributed to the loss of life.The Andrea Doria sank the following day on July 26, after rescue operations had concluded, resulting in a complete submersion of the ship. The aftermath saw debates about maritime safety regulations and the protocols for navigation in poor visibility conditions. The tragedy also impacted ship design considerations regarding safety features. Investigations into the circumstances of the crash revealed issues related to visibility and communication between the vessels before the collision, which led to significant changes in maritime law and safety practices.
