A four-switch panel called the airframe mounted accessory drive, or AMAD, sits on the left side of the B-2 Spirit’s two-person cockpit. The AMAD switches control the connection of the engines to the hydraulic and generator power of the aircraft. Several stealth bomber pilots at Whiteman Air Force Base, Mo., recently collaborated with the local high school robotics team to design and 3-D print the protective covers for the panels. Now, all 20 B-2s at Whiteman use the panel covers during flight. (U.S. Air Force photo by Staff Sgt. Kayla White)
