Cartwheel with asymmetric loading
"Unlikely to be repeated in squadron service as the external stores were loaded asymmetrically so that the weight difference helped the gyrations." (Safetypee #4)
This does not ring true. The detailed descriptions conclude with the aircraft entering a spin, although I am not sure why that was necessary and I wonder if we would have called it an incipient spin in my time.
I would have thought that, as has been mentioned already, the wingtip tanks were important and the racks of RP were useful to maximise the moment of inertia - no point in stinting on those loads.
But to have the wings loaded asymmetrically when committed to a spin would be looking for unnecessary trouble, even if you are Zuracowski.
