I was aware that she'd raised the flaps at too slow an airspeed, but I didn't know she had raised the flaps at successively lower airspeeds on each of her three go arounds. I was a little surprised at the suggestion that she was unassertive and could have asked to go back to approach. Certainly with a go around of a jet, towers tend to send them back to approach. But for smaller planes, I think they're likely to keep them in the traffic pattern. Before viewing this, I wouldn't have thought to ask to go back to approach. But in the future I'll keep that in mind as an option.
