A twin-fuselage aircraft has two main fuselages. Wing sections were built for Lancaster bombers and Hampden fuselages were overhauled. BNSF transports Boeing 737 fuselages from the Wichita, Kansas plant to Renton, Washington. Twenty-four aircraft were produced with redesigned front fuselages and dihedral added to the outer wing. KAI had previously produced wings and forward fuselages for F-15K and F-15SG. Later gliders with three-dimensional fuselages use a lightweight construction optimised for flight performance. This resulted in an aircraft with twin fuselages and five engines. The term is commonly used in connection with aircraft fuselages and automobile chassis. Many XVIs featured cut-down rear fuselages with bubble canopies. During the war it used wooden rear fuselages due to a shortage of metal. The last pre-suspension fuselages entered final assembly in early January 2020. Three "Myrsky" fuselages and several parts have survived. There were no privately owned Black Hawk fuselages available to acquire for the film.
