IMPERIAL WAR MUSEUM DUXFORD, England - Staff Sgt. Brent Deen, 48th Security Forces military working dog handler, is brought down by MWD Yyogi, a Belgian Malinois, during a demonstration at the Duxford American Air Day, Aug 19, 2011. The American Air Day provided the local community the opportunity to see what Airmen stationed in England do on a daily basis. The day included a mix of flying and ground-based activities that featured people and aircraft from Royal Air Forces Lakenheath and Mildenhall, which included F-15 Eagle and KC-135 Stratotanker flyovers.
