Two F-16 Fighting Falcons from the 332nd Expeditionary Fighter Squadron wait out a haboob, Sept. 9, 2008. Haboobs are sandstorms that result from the collapse of thunderstorms and the resulting downdrafts. The dust carried by a haboob can rise several kilometers in the sky, and winds can travel upwards of 30 mph. The F-16 in the foreground is deployed from the Air National Guard's 174th Fighter Wing, based in Syracuse, N.Y. The F-16 in the background is deployed from the South Dakota ANG's 114th FW.
