100 Missions Up North Exhibit DAYTON, OH (WYSO) - There are a lot of stories about what it was like to fight in Vietnam-books, movies and photographs-images of men with rifles in tall grass come easily to mind. But perhaps less known are the stories of those who flew plans over southeast Asia. A new exhibit at the National Museum of the U.S. Air Force focuses on the cultures and traditions of some of Vietnam's airmen. WYSO's Emily McCord has this story. © Copyright 2009, WYSO
