How much automation, how much pilot?
Automation is as much subject to failure as is the pilot, for the simple reason that the automation is designed by a human. An A320 that wouldn't let the crew flare for landing, writing off the airframe.
CAUSES: "The cause of the accident was the activation of the angle of attack protection system which, under a particular combination of vertical gusts and windshear and the simultaneous actions of both crew members on the sidesticks, not considered in the design, prevented the aeroplane from pitching up and flaring during the landing."
