Abstract
Abstract A delta-wing air craft comprises a main wing and a pilot''s cabin section forwardly of the main wing, the pilot''s section being detachable from the main wing and including a pair of auxiliary wings pivotably mounted about a vertical axis of the aircraft. The auxiliary wings form the apex of the delta-wing in the attached position of the cabin section, and are pivotable to a deployed position when the cabin section is detached to provide a glider wing surface for the detached cabin section.
