Two U.S. Air Force B-1B Lancers fly from Andersen Air Force Base, Guam, into Japanese airspace and over the Korean Peninsula, July 30, 2017. The B-1s made contact with Japan Air Self-Defense Force F-2 fighter jets in Japanese airspace, then proceeded over the Korean Peninsula and were joined by South Korean F-15 fighter jets. This mission is in direct response to North Korea’s escalatory launch of intercontinental ballistic missiles, July 3 and 28.
