Practice makes perfect: 446th maintainers rehearse Spark Tank pitch
Maintainers from the 446th Airlift Wing pitched their innovative battery cell extraction tool here to local Air Force Association members, community leaders and colleagues Tuesday, Feb. 11, as they prepare for the Air Force's Spark Tank 2020 competition in Orlando, Fla., later this month. Master Sgt. Robert Tingle and Master Sgt. Roy Puchalski teamed up to create a new tool that could revolutionize how maintainers around the world complete a routine task: battery cell removal for the C-17 Globemaster III aircraft.
