This is a very unique image from the assembly line at Boeing Aircraft Corporation's Vertol Division in Pennsylvania. The image features one of the Swedish Navy's first Vertol 107s as it was being constructed at the factory. The helicopter (most likely no. 13, 04063) is the second aircraft in the nearest line (behind 150935, a CH-46A of the US Marines).
