Tweak the KC-135 Stratotanker’s Windshield Wipers – Save Millions
From the Popular Mechanics website

The Air Force has discovered a simple engineering change to the venerable KC-135 Stratotanker could save it up to $7 million a year. Using computer modeling, the Air Force realized it could increase the aerodynamic efficiency of the converted jetliner by one percent by changing the orientation of the windshield wipers. The increased efficiency translates into greater fuel savings.
