A group of honorary commanders look out with mock amazement from the control room of the petroleum pump house operated by the 436th Logistics Readiness Squadron during a tour of the facility March 18, 2015, on Dover Air Force Base, Del. The facility moves fuel from large storage tanks to underground delivery stations on the flight line and the area being viewed is filled with a complicated maze of piping, pumps and specialized equipment.
