If you remember from history, the Spruce Goose was designed and built by Howard Hughes intended as a transatlantic transport for use during World War II. (It was not completed in time to be of use.) The Hughes H-4 Hercules is a prototype heavy transport aircraft designed and built by the Hughes Aircraft Company, and this move was interesting for a few different reasons.
The timing had to be expedited due to the fact part of the move went across a highway, so that highway had to be closed. The gigantic plane was dismantled into 4 different sections, with the fuselage weighing over 400 tons alone! The Spruce Goose had been delivered to the Evergreen Airport and Robbins and Co needed to carefully maneuver it over a mile to its new home at the Evergreen Aviation & Space Museum. There was an air show happening at the same time and became a big news event.
