Looking 4 POW/MIA Book from Coast to Coast

Please help if you can. I remember a guy on C2C last year that wrote a book about pow's still being held in either Vietnam or N.Korea. I don't remember too much about it other than I thought I'd wanted to read it. I made notes but something happened to them.

The title of the book had something to do with a code word U.S. pilots used. They would spell this code word in rice fields so U.S. satellites would see it and know they were still there.

Thanks in advance.

Wow.. not one person has any clue.. its too bad.. I would have made a great topic for discussion if i had more info on that book.

Day 2 and no one knows.. this is shocking. Heck I'm not even getting any hits here.

Come on guys.. help me out here!
