Doesn't really matter how she got into the airline it would appear that she has significant experience since and I doubt she was given a free ride through the Command process. I think what it does highlight is that professionals from all walks of life and yes even the steely eyed missile persons in the flight deck are under significant stress from things such as personal matters, changes in corporate culture, the drive to squeeze as much "productivity" out of flight crew and uncertainty about retirement incomes. She has made a decision that will impact on the rest of her working life. Don't be too quick to judge because in this day and age none of us know where our particular breaking point is.
