The self closing aircraft door includes two overlapping door panels and is attached to an outer skin of the aircraft by a plurality of suction cups. Each of the door panels comprises a net material at least partially surrounded by a flexible frame. Each of the panels also includes essentially parallel connecting rods comprising a plurality of magnetic and non-magnetic segments. The door is structured so that in the closed position, the magnetic segments in the connecting rods of the two panels join and thereby create a physical barrier to insects which might otherwise enter the aircraft cabin.
