I’m glad you liked it. It’s a great 2-part movie. The first part is called Jean de Florette. If you’re going to watch it (presuming you’ve never seen it before), you should start with Jean de Florette and perhaps make a 2-night film festival of it.
The pilots were too poorly trained to recognize and deal promptly and correctly with a stall. In the event of any in-flight malfunction such as this, the first reference should have been to the attitude gyros rather than to airspeed. Airbus airplanes are designed to fly at cruise with the center of gravity located relatively close to the aerodynamic center in the interest fuel efficiency; the trade-off being reduced static stability, i.e., the tendency to easily recover from a stall. There was an incident years ago where another poorly trained crew flew a DC-10 from the US to Spain with the aircraft stalling repeatedly most of the way but they survived because the high static stability of the DC-10 allowed the aircraft to recover repeatedly on its own, albeit with substantial structural damage.
