As the Task Force exercised while it sailed south, it became clear that there was a significant disparity between the RCS of different individual Sea Harrier airframes. Investigation revealed that this disparity was down to the amount of WD-40 (a spray oil used to repel moisture and inhibit corrosion) applied to the aircraft. Paint contaminated by WD-40 was found to be more reflective of radar energy.

Ça tient vraiment à pas grand-chose !
