Wesley Walker, a 354th Maintenance Squadron aircraft munitions systems specialist, await clearance to taxi at Royal Australian Air Force Base Williamtown, in New South Wales, Australia, March 24, 2017. Prior to the 18th Aggressor Squadron completing their final sortie in Exercise Diamond Shield, Walker was offered an opportunity to observe the mission of training and preparing Royal Australian Air Force fighter combat instructors, airspace battle managers, fighter intelligence instructors and fighter combat controllers of the RAAF Air Warfare Centre Instructors Course from a perspective he’s never seen before; from 30,000 feet in the air.
