Out with the bad, in with the good
Airman 1st Class Jeffrey Montgomery connects the waste suction hose to the lavatory service outlet on the underbelly of a C-17 Globemaster III Sept. 7, 2010, on Joint Base Charleston, S.C. Airmen on lavatory service duty first pump water into the tank to break apart waste particles making the removal process smoother. Once the waste is removed, "Blue Juice" is pumped back into the system which is a cocktail comprised of water, anti-freeze and an anti-smell agent. Airmen service every C-17 upon landing and sometimes before take-off. Airman Montgomery is an air transportation technician with the 437th Aerial Port Squadron.
