With only four hours of flight on its clock, an F-35 Lightning II from the 158th Fighter Wing out of the Vermont Air National Guard Base, South Burlington, Vt., receives fuel from a 434th Air Refueling Wing KC-135 Stratotanker from Grissom Air Reserve Base, Ind., over the Midwest Sept. 19, 2019. The 158th FW is the first Air National Guard unit to receive the aircraft, and will be the second operational F-35 wing in the U.S. Air Force, and will receive a total of 20 over the following months.
