    a segmented bubble window incorporating a transparent glazing in an upper portion of the bubble, and a door plug kick panel in a lower portion of the bubble;

    a door strut indent located along a lower periphery of the door plug assembly, wherein;

    the door strut indent accommodates installation of a strut extending from an interior of the door plug assembly to an exterior of the door plug assembly, wherein the door strut indent provides a pressurized seal around the strut; and
