Andrea Doria
On a summer night off Nantucket, two ships crossed under weak lights and trusted the same instrument to keep them apart. The Andrea Doria’s end would become a verdict on human judgment, radar’s promise, and the terrible speed at which confidence can fail.

Timeline
Andrea Doria enters service
**1951-06** — The Italian Line’s new flagship begins life as a symbol of postwar recovery and transatlantic prestige. Built for comfort and modernity, she is intended to represent a technologically confident Italy on the North Atlantic run.
Fog closes over the approach to Nantucket
**1956-07-25** — On the western Atlantic approaches, visibility deteriorates and the two liners converge on intersecting courses. Radar returns become the central basis for judgment on both bridges, making human interpretation the decisive factor.
Collision in the fog
**1956-07-25T23:10** — The Stockholm’s bow strikes the Andrea Doria on her starboard side amidships. The impact breaches the Italian liner and begins progressive flooding that will decide her fate.
Evacuation begins
**1956-07-26T00:00** — Passengers and crew move to muster stations as the ship lists more sharply. Nearby vessels answer distress calls, and the emergency becomes a race between evacuation and worsening stability.
Rescue platform formed by the Ile de France
**1956-07-26T01:00** — The Ile de France arrives and takes on a central role in receiving survivors from lifeboats and transfer operations. Her floodlit decks become one of the defining scenes of the rescue.
First casualty estimates emerge
**1956-07-26** — As survivors are counted and missing persons lists begin to form, the scale of loss becomes clearer. Later official and historical accounts converge on 46 deaths, though early tallies varied.
Andrea Doria sinks
**1956-07-26** — After more than ten hours afloat with fatal damage, the liner capsizes and disappears beneath the Atlantic. The wreck becomes an enduring marker in maritime history and salvage lore.
Official inquiries begin
**1956-07-27** — Italian and American authorities begin examining the radar plots, navigation decisions, and damage patterns. Testimony from officers and survivors becomes the basis for reconstructing the accident.
Inquiry findings issued
**1956-10** — The official analyses conclude that the collision was caused by navigational misjudgment under reduced visibility, with radar interpretation central to the chain of error. The findings become a reference point for maritime safety practice.
Radar and bridge practice reconsidered
**1957** — Shipping companies and maritime authorities use the collision as a training case for radar plotting and collision avoidance. The disaster pushes the industry toward more conservative procedures in poor visibility.
Survivors and the dead enter public memory
**1956-08** — Accounts, photographs, and reunion stories turn the sinking into a cultural memory of elegance undone at sea. The wreck becomes a symbol of both rescue skill and technological overconfidence.
Survivors reach shore
**1956-07-26** — Passengers are transported to New York and nearby facilities for identification, medical attention, and reunification efforts. The immediate emergency begins to stabilize even as the wider shock continues.
