The jettisonable door system further includes a lower hinge having a forward portion that is hingedly coupled to the airframe of the aircraft, the upper hinge having an aft portion that is releasably secured to a lower outboard plate with a lower pin. A rotation of the upper pin releases the upper hinge from the upper outboard plate and a rotation of the lower pin releases the lower hinge from the lower outboard plate.
