Yes getting the chance to spend time with them and listening to their stories changed my perception of oral history. I found out more information from them than I could have gotten from reading 100 books. I got the chance to go to an aviation museum with the pilot and we crawled around a B-17G. He explained every detail about the duties of the pilot and co-pilot. Then I was able to take the waist gunner on an honor flight trip as his guardian. We spent a few nights in the hotel bar discussing his time in POW camp Stalag Luft IV. I didn't intend to write the book but the stories were just so great I couldn't avoid it.
