Todd Bayles, REACT Cell engineer lead, holds a B-52 battery vent tube created using additive manufacturing to put the aircraft, B-52H 60-0015, back in to service as there were no spare parts available. This small plastic part had the potential to keep two massive B-52 Stratofortress’ on the ground after completing depot level overhaul. See story for the surprising figure of how much it was costing the Air Force to keep the aircraft grounded and how much the part cost to solve the problem. (U.S. Air Force photo/Greg L. Davis)
