Violet Jessop May Have Either Been the Luckiest or Unluckiest

Violet Jessop may have either been the luckiest or unluckiest woman ever to live. Jessop was a stewardess on a number of ocean liners. She began her career aboard the Orinoco in 1908 when she was 21 years old. In 1910, she started working on the White Star Line onboard the HMS Olympic. A year later, her troubles began. She was aboard the ship when it collided with the British warship HMS Hawk while the two were sailing through a narrow straight. Fortunately, neither vessel sank and no one was hurt. While the Olympic was being repaired, Jessop signed on with the ill-fated RMS Titanic. When it hit an iceberg in the North Atlantic, she was fortunate to get into a lifeboat and survive the ship's sinking. But Jessop couldn't stay away from the sea. During World War I, she served aboard the HMHS Britannic, which hit a German mine and sank. Although she nearly drowned, she did manage to escape. She earned herself a nickname in the process-newspapers across England dubbed her "Miss Unsinkable." So was Jessop lucky or unlucky? The fact that she lived to the ripe old age of eighty-three should give you some clue!
