A roadable aircraft may be registered and driven as a motorcycle on the roadways, does not require that any parts be "left behind" at the airport when configuring to roadable use and does not require removing portions of the aircraft and towing them behind. A foldable and collapsible wing comprises a number of wing ribs, which are hinged to a main forward spar. To fold for road usage, the wing ribs fold about a hinge fitting to collapse against the wing spar. To maintain tension on the wing skin (to prevent flutter) tensioning bladder(s) may be used to keep the fabric taut. Once retracted and folded, the wings align with tail booms to form a compact and aerodynamic package. The ductless fan may be provided with a center-mounted extraction fan ducted to inlets along the fuselage to draw low energy air in toward the fuselage and thus prevent boundary layer separation.
