Aircraft commander
U.S. Air Force Capt. Ryan Turner, 93rd Air Refueling Squadron KC-135 Stratotanker pilot, and Capt. Ntungwe Sobe, 384th ARS KC-135 aircraft commander, prepare to take off at Eielson Air Force Base, Alaska, Aug. 30, 2019. The responsibility of an aircraft commander is earned through several hours of flying and training, and can take two to three years from when pilots first gain their wings. To become a pilot, students must understand the basics to theory of flight, air navigation, meteorology, aircraft operating procedures and mission tactics.
