I must have missed this post during the Christmas-New Year's break. Great story and even greater picture. Hopefully you can explain to him that we do hold these men in awe - even though most don't really want to hear it. Just make sure he knows we remember and are thankful. (Same to all you guys on the forum!)
Perhaps the way to go with an interview is with his strengths. We know the history (as you pointed out, better than he) - I would ask him about the things he felt and did. I think some of the more mundane things might be interesting - How many pairs of clothes did he jump with? What was the discipline in the ranks like? (e.g. What happened to the guy who discarded the Bazooka - that's not like throwing away some useless piece of personal gear.) Did the rank and file take discipline into their own hands in some cases? Was there a great deal of hazing? etc.
Just some thoughts.
