A U.S. Air Force B-1B Lancer assigned to Andersen Air Base, Guam, performs a landing at Osan Air Base, Republic of Korea. Sept. 21, 2016. The B-1 is the backbone of the U.S. long-range bomer mission and is capable of carrying the largest payload of both guided and unguided weapons in the Air Force Inventory. The flight was the closest a B-1 has ever flown to the border between the Republic of Korea and North Korea. (U.S. Air Force photo by Senior Airman Dillian Bamman)
