converting from a head-on at high speed in 67 wing, pulling hard to convert to stern attack with high alpha while simultaneously moving the wings to 45. Somebody with a better grasp of aerodynamics might be able to explain what happens in these conditions
You'd end up with a very high speed stall. Swept wings produce low lift/drag ratio but stall at high alpha. Unswept wings produce high lift/drag ratio but stall at low alpha. So if he moved wings forward at high alpha and high speed, and assuming he was maintaining constant alpha and power, lift would initially increase rapidly, giving marked decrease in turn radius and increase in g, and then a very sudden stall. Given the high directional stability of the Tornado probably the outside wing would have stalled first so they probably flicked upright, but not necessarily!
