In 1912 the RMS Titanic sank in the North Atlantic, killing more than 1,500 people, and becoming the most famous maritime accident in the 20th century. But unknown to many, Titanic’s sister ship met a similar fate as well. The HMHS Britannic was a hospital ship owned by the White Star Line and was active from the years 1914-1916. On November 21, 1916, she was carrying 1,065 people on board when the hull struck an underwater mine. Britannic leaned drastically to the starboard (right) side, and within 55 minutes was completely underwater. Unlike her famous sister Titanic, the Britannic did not break in half. In total 30 people were killed during the sinking. The wreck was discovered off the coast of Greece in 1975 and remains in wonderful diving condition.
