Something you might not know about the Kennedy family...

Aside from the tragic assassinations of John F. Kennedy in 1963 and his brother Bobby Kennedy in 1968, their brother Ted Kennedy ran his car off a bridge in Chappaquiddick in 1969, and managed to escape - but his passenger, Mary Jo Kopechne, was not so lucky - she drowned, leading to conspiracy theories that Kennedy had driven the car into the water on purpose. In 1999, JFK's son died in a plane crash with his wife and her sister.
