A breakout box and line replaceable unit extension cables lie on a counter in the avionics shop at Misawa Air Base, Japan, Aug. 1, 2016. The device was created by the 35th Maintenance Squadron avionics flight to help speed up continuity checks on LRUs which inspect the integrity of electrical pathways. LRUs are aircraft parts found in F-16 Fighting Falcons that allow a pilot to interact with the jet. (U.S. Air Force photo by Senior Airman Jordyn Fetter)
