This is How Boeing Moves Massive Airplane Parts

Get in the driver seat and see how Boeings Long Load Crew moves spars and stringers over 30 meters long for the Boeing 777, 767, and 747. The steer car is attached to the back of a long truck that hauls large structural components for wings about 70 miles (113 kilometers) from Boeings Fabrication facility in Frederickson, Washington to its factory in Everett.
