Capt. Quinton Keigley, 14th Medical Operations Squadron, pauses before an F-16 Fighting Falcon sortie on the flightline at Luke Air Force Base, Arizona. Keigley is attending Top Knife II at Luke where flight surgeons and physiologists spend two weeks in academics, simulators and high “G” flight to better understand the effect of high “G” aircraft on aircrew members. Keigley was just recognized as the 2015 AETC Flight Surgeon of the Year. (U.S. Air Force photo)
