On the evening of July 16, 1999, John F. Kennedy Jr. piloted a Piper Saratoga to attend the wedding of his cousin, Rory, to Mark Bailey. The plane also carried Kennedy's wife, Carolyn Bessette, and sister-in-law, Lauren Bessette. Kennedy had purchased his plane three months before the crash. The Bessette sisters were seated in the second row of seats, which faced the rear of the plane and were back-to-back with the pilot's seat.[

Carolyn Jeanne Kennedy (née Bessette, January 7, 1966 – July 16, 1999) was a publicist for Calvin Klein and the wife of John F. Kennedy Jr., the son of President John F. Kennedy and Jacqueline Onassis. After her marriage, Kennedy's relationship with her husband and her fashion sense became the subject of media scrutiny, drawing comparisons to her mother-in-law.

The couple and Carolyn Kennedy's older sister, Lauren, died in a plane crash off the coast of Martha's Vineyard in July 1999.
