Most people have heard of the very famous Titanic, but very little know she had a sister ship, named the Britannic. Built and launched after the tragic loss of her sistership -the famous Titanic. The Britannic never crossed the Atlantic carrying the rich and the poor to the New World. She was converted into a hospital ship and made six voyages to the Mediterranean, evacuating thousands of wounded soldiers from the battlefields of the Eastern Front during World War I. Deemed more "unsinkable" than the Titanic due to the modifications of her design, she was lost in only 55 minutes after an explosion caused by a German mine. The Britannic was the largest British ship lost during the conflict and remains the largest sunken ocean liner in the world. The enormous wreck was found in 1975 by Jacques Cousteau near the Greek island of Kea in the Aegean Sea.
