Spaceflight Now's NASA still looking for new human spaceflight chief says:
In August, Bridenstine said NASA is “looking wide and far” for a new human spaceflight chief at NASA Headquarters.
“We’re doing a nationwide search,” he said Aug. 21. “The challenge is … when it comes to these kind of activities, there’s very few people on the planet that have experience with human spaceflight missions, that have experience managing large programs. We are, at this point, wide open, looking at all the possible alternatives of various people with various types of expertise that could lead human exploration and operations. So at this point, we have not even begun to narrow the field.”

Bowersox† said that once NASA names the permanent head of the human exploration and operations mission directorate, the new manager will be charged to determine a new target launch date for Artemis 1, with a schedule that includes extra time to address unforeseen problems that may crop up during testing.
“Right after naming a permanent associate administrator, we expect, within a month or two, that person would have time to come up with a date that they can be ready to commit to Congress on,” Bowersox said Wednesday in response to a question from subcommittee chair Rep. Kendra Horn, D-Oklahoma.
†Ken Bowersox... became the acting associate administrator for NASA’s human exploration and operations mission directorate after Gerstenmaier’s ouster in July.
Now this certainly seems like a highly desirable position, who wouldn't want to be a new NASA employee "charged to determine a new target launch date for Artemis 1" and "be ready to commit to Congress"?
Question: How often has NASA brought in people from outside to be responsible for making important decisions?
