More than 16 million American's fought in World War II. There's only about a million of them who are still alive and they're all older than 80. Hundreds are dying each day. A non-profit group has made it their mission to honor these remaining veterans by flying them to Washington, D.C., to visit the World War II memorial. The trip isn't something many veterans at this age can do — or afford — on their own. Since the first "Honor Flight" in 2005, groups in almost every state have followed suit and more than 100,000 vets have taken the journey.
