A (bird tail type) airplane tail section (compound delta wing design) which includes: movable wing assemblies (92), attached to a center boom pitch assembly (76). Each rear wing assembly (92) is connected to a hydraulic control system (74) that selectively moves each rear wing assembly (92) in an arc on opposite sides of the boom pitch assembly (76). Each rear wing assembly (92) includes two pivoting parabrakes (32) mounted on the top and bottom surfaces of the wing assembly (92) that moves between a flush mounted configuration to an extended, air brake configuration. Hydraulic cylinders connected to the aircraft hydraulic system (74) are used to control the wing assemblies (92) and parabrakes (32). Disposed between the proximal end of the boom pitch assembly (76) and the aircraft fuselage is the pivoting joint (100) that enables the boom pitch assembly (76) to rotate and to pivot in all direction to simulate the movement and function of a bird's tail, when a bird is in flight.
