An aircraft or sailboat structure and the method of manufacturing it in which the wing is formed of an elongated leading edge core of lightweight formable cellular material having an aerodynamically configured semi-circular forward surface and a substantially planar rearward vertical surface. A thin structural impervious skin is bonded to the leading edge core forward surface, an elongated trailing edge core formed of lightweight formable cellular material with a thin structural impervious skin bonded to the trailing edge upper and lower aerodynamic surfaces. The trailing edge portion has a substantially vertical forward surface, the vertical surfaces of the leading edge and trailing edge portions being secured to each other to complete the wing. The structural skins are secured to the core portions employing a bonding material and a molding system in which the skins are held in contact with the cores without sufficient pressure, temperature, and time to secure complete bonding.
