Like any safety manager, Angelia Walker takes it as a good sign she's busy. Walker manages the Safety, Reliability and Quality Assurance Policy Assessment Department office at NASA's Marshall Space Flight Center in Huntsville, Ala. Propulsion engineers stop by to verify data. Supervisors drop in to check on a report. Managers at NASA headquarters in Washington call for updates, according to a NASA news profile.
"Everyone's asking questions, keeping up a constant flow of information," Walker says. "That's the first sign of a positive safety culture and a healthy engineering environment."
