No water, no fuel, no gas, no problem!
Airman Jeremiah Cottinghan, 2nd Civil Engineer Squadron Water and Fuel Systems Maintenance, flushes a hydrant on Barksdale Air Force Base, La., Sept. 26, 2014. Flushing the system helps prevent corrosion caused by extended exposure to the elements which makes the hydrants ineffective. (U.S. Air Force photo/Airman 1st Class Mozer O. Da Cunha)
