Kirtland Air Force Base, New Mexico --   The Air Force Nuclear Issues Resolution and Integration Board held its winter meeting at the center on Feb. 6, 2020, at Kirtland AFB, New Mexico. While there, board members stopped for a photo in front of the Kirtland AFB Trestle Facility. A landmark of the Cold War, it was built in the 1970s to test the effects of an electromagnetic pulse on aircraft and is considered one of the largest all-wood structures in the world, right down to its bolts.
