Aircraft having Versatile Door Systems

An aircraft comprising:

• an airframe having an aircraft opening;
• and
• a versatile door system coupled to the airframe, the door system including:
• a forward door assembly including a forward hingeable door and a forward slidable door, the forward hingeable door hingeably coupled to the airframe proximate a forward location of the aircraft opening, the forward slidable door slidably coupled to the forward hingeable door;
• and
• an aft door assembly including an aft hingeable door and an aft slidable door, the aft hingeable door hingeably coupled to the airframe proximate an aft location of the aircraft opening, the aft slidable door slidably coupled to the aft hingeable door;
• wherein, in a closed configuration, the forward hingeable door, the forward slidable door, the aft hingeable door and the aft slidable door are securably disposed within the aircraft opening;
• and
• wherein, the forward hingeable door, the forward slidable door, the aft hingeable door and the aft slidable door are individually operable to collectively provide access to a selectable width of the aircraft opening.
