That's a horrible assumption to blanket all pilots with. She was signed off and legally had every qualification to fly in that airspace. She flew with an instructor, and DPE who saw that she was perfectly capable. Unfortunately, on this day she was probably feeling pressured, overwhelmed and wasn't able to execute a landing that she had done 100s of times before.
With that being said, I flew into a Class B airport multiple times in an airplane I had never been in before 1 month after obtaining my PPL with no problems. Blanket statements like that are not accurate.
Also don't forget, this could happen to any pilot on this board. Alls it takes is some extra pressure combined with a lack of sleep or food, have to pee, other worries on your mind, or just a bad day and you could find yourself in this same situation in what others have described as a very unforgiving airplane.
