"It is a much different culture and society then our own," he said. "I can't really go into much detail other then we are trying to do the best we can to help the people of Afghanistan, but I believe they must work to make their country what they want it to be."
Hanke is one of 73 members of the military Schmidt has "adopted" over the last seven years, from every branch but the Coast Guard. And to those troops have gone hundreds of journals filled out by Delta passengers -- some have gotten five or six.
Schmidt said that in five years of filling journals she's gotten only two formal complaints to Delta from passengers who thought she was making a political statement.
But for Schmidt, who said she has voted both Democrat and Republican, her effort isn't about the war, it's about making sure the men and women who have volunteered to serve the United States get the support they need to do their job and stay safe.
She said she's careful to abide by Delta's only rule -- no journals on international flights -- and to hold her tongue when someone expresses displeasure about the journals.
"I'm well aware of what I get to do in the airplane is a privilege," she said.
While some people simply pass on the journal to others without leaving an entry, most passengers are enthusiastic participants, she said, and most have some connection to someone who is in the military.
"I think that's why everyone's so fascinated by my desire to support the military," she said. "I run into soldiers every single day through my job."
Delta spokeswoman Gina Laughlin told ABCNews.com that Schmidt had the full support of the airline and was one of many flight attendants that make a point to volunteer outside work or even during layovers.
"We have very compassionate employees who do unique things in the communities around the world," she said. "How can you not support that?"
