Nellis Raptors resume flight operations

A U.S. Air Force F-22 Raptor takes off Sept. 21, 2011, at Nellis Air Force Base Nev. The flight was the first since an Air Combat Command directed stand-down of the entire F-22 fleet May 3, 2011. The Raptors were grounded as a safety precaution, following 12 separate reported incidents where pilots experienced hypoxia-like symptoms. Officials remain focused on the priorities of aircrew safety and combat readiness. The return-to-fly plan implements several risk-mitigation actions, to include rigorous inspections, training on life-support systems and continued data collection. (U.S. Air Force photo by Tech. Sgt.
