Senior Airman Chad Helminiak, 60th Aircraft Maintenance Squadron aerospace propulsion journeyman, and Staff. Sgt. Randolph Quarteroni, 725th Air Mobility Squadron aerospace propulsion craftsman, lower a C-5M Super Galaxy engine into place June 6, 2019, at Dover Air Force Base, Del. The engine needs to be balanced from all sides while being lowered and raised. To accomplish this, Airmen must be able to communicate effectively as a team while cranking and checking the scales attached to the engine. (U.S. Air Force photo by Senior Airman Christopher Quail)
