Maintainers ensure B-52 fit for flight
Staff Sgt. Daniel Palmer, 2nd Maintenance Squadron fuels systems, places a ventilation dock inside a B-52H Stratofortress on Barksdale Air Force Base, La., Feb. 8. When a fuel tank needs repairs, sealant is placed on it to prevent leaking. The ventilation dock transfers warm air to the fuels systems to make the sealant harden faster.
