It's amazing how graceful/forgiving the A330 behaves below its flight envelope (stalled, storm and low airspeed)?
Before this incident if you asked me if a transport can be controlled at ~30kts in a storm then I would guess no, probably tumble and break up. Remarkably the reality is yes albeit requiring aggressive stick inputs to maintain level wings!
Was there a special reasons why AF447 remained controllable at ~30kts? Did the free fall/stall (100+kts vertical) acting on the superstructure provide aerodynamic stability even thought the wings were not flying?
Why did asymetric engine thrust/drag not induce a spin?
Why did the ailerons/rudder generate enough force to keep the a/c in a graceful attitude albeit oscilating in roll?
