was a good idea

I wish I'd have thought of it. :-)
The ailerons were ineffective even with the spoilers assisting. So I kicked
hard rudder. At that slow airspeed, the rudder travel isn't limited. The
swept wing snapped faster than Sister Mary Holysmoke can hit your knuckles
with a ruler.

Can you imagine making that recovery inverted?

This is something I've pondered. During mach tuck, the shock waves cause the
nose to pitch down despite the control inputs. If I went inverted during
recovery, wouldn't the inverted nose pitch up? Then the plane would
decelerate, the shockwaves would dissipate, and control would be regained.
