And, as an additional curiosity (minor for fixed wing but perhaps not so for rotary), there is a phenomenon described as high speed stall associated with VERY high pitch rates (scratchy memory suggests in excess of around 70 deg/sec). A stable vortex can form along the leading edge and angle of attack values significantly in excess of "normal" stalling angles are possible.
As I recall I first read of this in an RAeS tech report ?
