A very early DC-3, among the oldest still in existence. Originally delivered to United Air Lines, way back in 1936, as NC16071. After a long and varied career it was acquired by Skyways Inc. in 1969 as N655GP, and as such it made its way to Europe in the early 1970s. It was mostly based in Ireland while operated by several companies. In March 1976 it was registered as EI-AYO, and then sold to the Science Museum in late 1978.
