Kali, a pet who traveled to the Korean Peninsula on space available travel, is scanned for a microchip after arriving at the the Osan Air Base passenger terminal, Republic of Korea, March 2, 2015. After five years in the works, the 731st Air Mobility Squadron passenger terminal welcomed its first four-legged passengers on a new program allowing service members to fly their pets to the Peninsula via the "Patriot Express."
