I talked to Adrian Cronauer on my show this afternoon. You know him as the guy Robin Williams played in “Good Morning Vietnam.”

Now he works for the Defense Department in the Office of Missing Personnel, which continues to look for American servicemen and women who are still missing in action from World War II up through the current war in Iraq. He’s in St. Louis this weekend to meet with members of families who still have someone unaccounted for, and we talked about the science and technology that’s used to find them. He also explained a little bit of the history of “Good Morning Vietnam,” which originated as a script he wrote for a TV sitcom.
