U.S. Army Pvt. Ben Stocker, CH-47 Chinook helicopter crew chief with the 2nd Battalion, 135th General Support Aviation Battalion, Colorado National Guard, looks out over the Colorado front range west of Fort Collins, Colo., as they fly toward an area affected by the flood waters after delivering food and water to Colorado residents that have been affected by the floods but are allowed to stay with their homes, Sept. 17, 2013. What is being dubbed "Operation Centennial Raging Waters" is likely the biggest rotary-wing airlift mission since Hurricane Katrina and has become a complete neighbors helping neighbors effort with state National Guards from Colorado and Wyoming, active duty units from Colorado as well as search and rescue units from all over the country.
