Lt. Col. Thad Middleton, 9th Air Refueling Squadron commander, taxis a KC-10 Extender on the Travis flightline Sept. 11. A 22-aircraft "freedom launch" took place at Travis AFB, Calif., Sept. 11, 2013. Seven C-17 Globemaster IIIs, 11 KC-10 Extenders and four C-5B Galaxies from the 60th Air Mobility Wing launched consecutively over 36 minutes to take part in Air Mobility Command missions. The first plane in the lineup, a C-17, launched at 8:46 a.m., the same time terrorists crashed American Airlines Flight 11 into the North Tower of the World Trade Center in New York City 12 years earlier.
