Video goes viral of JFK enjoying a summer weekend only months before his death

Footage of President John F. Kennedy on vacation only four months before he was assassinated has been getting attention recently on the Web.

Although the John F. Kennedy Presidential Library and Museum released the 15-minute silent video on its website in 2011, the sweet summer footage is only now getting popular online. Some outlets have called it never-seen footage, but the spokesperson for the John F. Kennedy Library Foundation confirmed the footage has been open in the foundation's collection "for years."

The video shows Kennedy with his young family on a carefree summer weekend 50 years ago on July 27-29, 1963, in Hyannis Port, Mass.

The 46-year-old president is seen teeing off for a round of golf and riding a golf cart to the presidential yacht Honey Fitz, where his daughter, Caroline, jumps off to join the president for a swim. Later she is seen in her pink bathing suit on her father’s lap.

Jacquelyn Kennedy appears in the video in her trademark sunglasses with her daughter on the yacht.

The young family laughs and relaxes in the video in what turned out to be the final summer of the president’s life.

Kennedy was killed in Dallas while riding in his motorcade on Nov. 22, 1963. Daughter Caroline has taken up the family mantle with her nomination to be the U.S. ambassador to Japan.
