Todd Bayles, an engineer in the Reverse Engineering and Critical Tooling Lab, works on a computer-aided design (CAD) of a B-52 battery vent outlet. Two Boeing B-52 Stratofortress' were in need of the parts in order to meet their depot maintenance deadline and REACT engineers were able to reverse engineer the parts to help the B-52 team deliver the aircraft on-time.
