And reduced wing sweep. Overly aggressive rudder application or rudder malfunction is usual culprit. Early days of jet flying in military jets could result in loss of airplane. Not normally a catastrophe in mildly swept civ aircraft.
Wing sweep, yes. Flying RC models years ago I found that I could roll an aerobatic plane having no dihedral at all, but about 5 degrees of sweep, using rudder alone. I once launched the thing with the aileron servos disconnected, but recovered it that way. Wasn’t pretty, but I got it on the ground in one piece.
