A flying piece of World War Two history landed in central Iowa this week, allowing some people to climb aboard for an expensive ride into the past. Its polished aluminum skin gleaming, the restored B-25 bomber known as “Old Glory” once flew missions over Europe and now flies passengers in machine gunner positions for 300-dollars a person. Bill Harrison of Tulsa, Oklahoma, is the pilot. He says the rare warplane carries no price tag:Interviewed at the Des Moines International Airport, Harrison says his mission isn’t to glorify war but to recognize those from the so-called greatest generation who sacrificed their lives to preserve democracy. This preserved B-25 is among 20 in the world still flying.The airplane was built in Kansas City in 1944. After its service during World War Two, it was used as a fire bomber, a corporate transport, and was eventually taken apart and stored.
