The only time I saw Nancy admit to being wrong was when she finally admitted recently that all these years she didn't know that Dec and RA (which she still thinks stands for Right Angle) and Alt and Azi were the same thing. When confronted with the small detail that this renders all of her observations over the years as to positions of planets, the moon, the sun and the stars invalid, she ignored the issue. She also never apologized to the people that have been censored, banned and insulted over the years for pointing out what we all knew, that she didn't have a clue how to interpret coordinates. Thats as close as any of them have ever come to admitting they were wrong.
