Air France 447 went down over the Atlantic in 2009.

The fly-by-wire A330 incorporates technology that prevents the airplane from entering a stall, but during a complete loss of airspeed information, however, the system reverted to manual control.

The final report said said the pilots were “completely surprised” by technical problems experienced at high altitude and engaged in increasingly de-structured actions until suffering “the total loss of cognitive control of the situation.”

CEO of the Flight Safety Foundation has been recorded said pilots generally manually manipulating the controls for only three minutes:one minute and 30 seconds each for take-off and landing.

“We are moving towards automated operations where the pilot isn’t even permitted to fly. That means the first time in your career you will ever feel what an aircraft feels like at 35,000 feet is when it’s handed to you broken.”
