U.S. Air Force Airmen from Whiteman Air Force Base, Missouri, and the Royal Australian Air Force perform a foreign object debris walk at RAAF Base Tindal, Australia, March 22, 2016. The FOD walk was conducted during a training mission where a B-2 Spirit conducted an engine running crew change at the base. The B-2 was one of three that were deployed to the Indo-Asia-Pacific region from March 8 through 29 to enhance bomber crew readiness and proficiency and to integrate capabilities with key regional partners. U.S. Strategic Command bombers regularly rotate through the Indo-Asia-Pacific region to conduct theater security cooperation engagements with U.S. allies and partners and demonstrate a shared commitment to promoting security and stability in the region.
