Charlotte added another retiree Thursday, one finishing a high-flying career after 35 years. Delta Air Lines’ last DC-9 arrived at Charlotte Douglas International Airport and took up residence at the Carolinas Aviation Museum. Built in 1979, the aircraft is the latest addition to the growing fleet at the museum, which includes the fuselage of the “Miracle on the Hudson” jetliner that ditched five years ago without any loss of life to the 155 aboard. Shawn Dorsch, president of the Museum, said the plane is a key addition to the museum’s fleet because it’s an artifact that will tell a story about the development of commercial aviation in the 20th century. “This makes us a player in the commercial-aviation space as a museum,” he said.
