Herb Weatherwax charms visitors each of the three days a week he volunteers at a memorial for the USS Arizona, a battleship that sank in the 1941 Japanese attack.

The 96-year-old retired electrician is one of four former servicemen who lived through the aerial bombing and now greet people at the historic site.

Their numbers are dwindling. The three others are also in their 90s.

During the week, Weatherwax is joined by Sterling Cale, a hospital corpsman assigned to the shipyard dispensary in 1941, and Alfred Rodrigues, who was stationed at the mouth of Pearl Harbor.

On the weekend, USS Pennsylvania survivor Everett Hyland greets visitors.

This Saturday, they will join a few thousand guests for a public ceremony remembering those who died in the attack 72 years ago.
