USS Indianapolis survivors gather for reunion

Thirteen survivors of the USS Indianapolis attended an annual reunion downtown Sunday.

This week marks the 69th anniversary of the sinking of the World War II destroyer. About 300 sailors died when the ship was struck by Japanese torpedoes on July 30, 1945. More than 500 more men died during the next four days at sea, until the 317 remaining soldiers were rescued.

"It's nice to see the guys that are still here and we also come back to honor the fellas and buddies that didn't make it," said survivor Art Leenerman.

The incident marks the single worst disaster in U.S. naval history. Less than 40 of the survivors are alive today.
