The upper door assembly may comprise a first set of doors and a second set of doors therebeneath with an air lock inbetween, the upper door operating system including a motor and a first door actuator connected to the first set of doors and a second door actuator connected to the second set of doors and an interlock within a controller to prevent simultaneous opening of the first and second doors.
