On 16 July 1999, John F. Kennedy Jr. dies when the Piper Saratoga light aircraft he was piloting crashed into the Atlantic Ocean off the coast of Martha's Vineyard, Massachusetts in hazy conditions. His wife, Carolyn Bessette, and sister-in-law, Lauren Bessette, were on board and also killed. The NTSB concluded that the crash was caused by spatial disorientation resulting in pilot error.
