Eventually, all General Dynamics Fighting Falcons in service will make one last manned flight to the Boneyard, where a select few will refashioned with new equipment and an orange paint job on the horizontal and vertical stabilizers. Fitted with a Boeing-designed Drone Peculiar Equipment kit, these aircraft will be capable of unmanned flight and used for target practice. The process of optimizing the life cycle of such resource-intensive machines is an example of the circular economy in the heavy-industry sector. The Boneyard's remanufacturing process makes the most out of the planes that sit at the airfield. Precious parts are dismantled and reused in the Air Force and entire aircraft can be reassembled and put back into service. At the end of the life cycle, they can be scrapped for steel and aluminum recycling. This image is part a cover story, "The End of Trash," in National Geographic magazine.
