Senior Airman Ian Newkirk moves cement to evenly fill holes on a taxiway Sept. 22 at Ali Base, Iraq. Extreme heat, along with normal wear and tear, can cause cracks or potholes to form, making portions of the flightline unsafe for aircraft. Airman Newkirk, a pavements and construction equipment apprentice with the 407th Expeditionary Civil Engineer Squadron, is deployed from Malmstrom Air Force Base, Mont.
