For increasing the cargo capacity of an airplane of given weight, the cargo space is formed by a plurality of parallel tubes having their lengths extending spanwise of the wing, so that such cargo-carrying space is generally coextensive with the lift-producing airfoil. Auxiliary lift-producing fans may also be spaced spanwise of the wing, and the ground effect of such fans may be augmented by skirts depending from the wing. Propulsion thrust engines are also spaced spanwise of the wing to distribute thrust loading. The airplane wing is tilted downwardly spanwise so that containerized or particulate solid cargo or liquid cargo can be supplied to the cargo tubes through the lower wing tip, and such cargo can be removed from the cargo tubes by gravity or assisted by air under pressure to fluidize or expel the cargo. The wing may carry a plurality of spaced parallel fuselages.
