On November 21, 1916, Britannic , the sister ship to the Titanic, sank in the Aegean Sea, killing 30 people. In the wake of the Titanic disaster, the White Star line had made significant modifications to the design of the ship, but on its way to pick up wounded soldiers near the Gulf of Athens, it was rocked by an explosion causing even more damage than that which had sunk the Titanic. Many of the dead were from some of the crew who attempted to launch life boats while the Captain tried to run the ship aground. The life boats were sucked up into the propellers, killing all of those on board. The cause of the explosion is still unknown, but many suspect it hit a mine.
