And bad pilot training, if I recall correctly.

Crashes caused by pilots failing to execute proper stall recovery procedures are surprisingly common, and similar accidents have happened before in aircraft with traditional control schemes, so I’m skeptical that there are any hardware changes that would have made much difference. The official report doesn’t identify the hardware or software as significant factors.

The moment to avoid the accident was probably the very first moment when Bonin entered a steep climb when the plane was already at 35,000 feet, only 2000 feet below the maximum altitude for its configuration. This was already a sufficiently insane thing to do that the other less senior pilot should have taken control, had CRM been functioning effectively. What actually happened is that both of the pilots in the cockpit at the start of the incident failed to identify that the plane was stalled despite the fact that (i) several stall warnings had sounded and (ii) the plane had climbed above its maximum altitude (where it would inevitably either stall or overspeed) and was now descending. It’s never very satisfying to blame pilots, but this was a monumental fuck up.

If the pilots genuinely disagree about control inputs there is not much that hardware or software can do to help. Even on aircraft with traditional mechanically linked control columns like the 737, the linkage will break if enough pressure is applied in opposite directions by each pilot (a protection against jamming).

I'm reminded of the Apollo moon landing where the computer was rapidly rebooting and being in an OK-ish state to continue to be useful almost immediately
