A bidirectional flying wing maximizes efficiency and reduces sonic boom during supersonic flight. The flying wing has bilateral symmetry across two perpendicular planes and a substantially isentropic compression bottom surface that minimizes the shock wave projected downward during flight. The flying wing may be rotated to provide a high aspect ratio and a low sweep angle during subsonic flight.
