(CBS News) The last of World War II's great ships, the USS Iowa, holds special significance for two men working to preserve the vessel.
The battleship will soon become a floating museum in Los Angeles, and David Canfield and Mike McEnteggert have been working to make that happen to preserve the ship's history - and to help them heal from a devastating memory.
Canfield and McEnteggert were serving together when an explosion on April 19, 1989 ripped through a gun turret, killing 47 on-board. The two men recently revisited the ship - and the profound memory of the event - with CBS News.

The floating museum is slated to open next month.
