An aircraft vehicle includes a body, including a front portion and a rearward tail portion, a single panel door constructed and arranged to close an access opening defined in a lower portion of the body, and a linkage between the body and the door. The linkage is constructed and arranged to move the door generally rearwardly and upwardly when the door is moved from a closed position to an opened position, so that the door is positioned below and adjacent to the rearward tail portion.
