A method and apparatus for transporting containers in an aircraft. A number of containers is loaded into the aircraft. The aircraft is comprised of first and second outer planar structures, a number of planar structures located between the first outer planar structure and the second outer planar structure, a wing, and a support structure. The first outer planar structure, the second outer planar structure, and the number of planar structures are substantially parallel to each other, are coupled to each other to form a fuselage structure, and are configured to receive the number of containers. The support structure connects the wing to a first bottom end of the first outer planar structure, a second bottom end of the second outer planar structure, and a number of bottom ends of the number of planar structures. The aircraft is operated to transport the number of containers to a destination.
