A window element has a cover pane which is substantially flush with an outer skin of an aircraft or other transport, achieving a fluid-dynamically favorable, substantially unbulged exterior surface. As a result of the presence of an additional back-ventilated cover pane arranged in front of the actual outer pane of the window element, a fluid-dynamically favorable integration of the window element into the outer skin of an aircraft fuselage airframe is achieved. Any deformation, such as any buckling or bulging of the outer pane of the window element, as a result of a difference in pressure between the interior of the aircraft fuselage airframe and the exterior space at cruising altitudes, has no fluid-dynamically disadvantageous effect. The outer pane is covered by the cover pane which remains substantially undeformed with respect to the outer skin of the aircraft fuselage airframe, for example. Any deformation of the cover pane is largely eliminated by back-ventilation.
