There are only two things that I could think of which would result in her being taken off:
1) The entire flight team refusing to fly with her due to low confidence in her skills, or
2) An affair with one of her subordinates.
And if it were (1), I think there would have been several weeks of analysis and cajoling before her commander gave up.
She does appear to be attractive.
3) An affair with all of her subordinates.
Perhaps she wouldn’t put out for the good Colonel..
