• and
• wherein the barrier door is movable between a stowed position and a deployed position, the stowed position comprises the first panel and the second panel folded together in an overlapping configuration and positioned in the gap in the frame and the deployed position comprises the first panel and the second panel positioned in a non-overlapping configuration and positioned out of the gap and extending across the opening.

A method of deploying a barrier door within an interior of an aircraft, the method comprising:

• positioning the barrier door in a stowed position within a gap in a frame and with a first panel and a second panel of the barrier door in a folded configuration with the first panel and the second panel positioned on a front side of an opening in the aircraft;
• pivoting the first panel and the second panel about a frame hinge from the front side of the opening to a rear side of the opening and the frame hinge connects the barrier door to the frame;
• and
