It should be noted that for the Air Show, the Airbus had most of it’s software safety features disabled and on top of that, the pilots flying the plane actually didn’t know the airport they were performing at. The latter is a major red flag.
In the end, software didn’t bring down that flight (as in, the software didn’t pitch the plane down into the ground). Disabled safety features stopped the plane from correcting a situation it would normally be protecting pilots from. And the pilots where unaware of any obstructions past the runway. Coupled with long spool up times for jet engine (any jet engine, I might add), and that flight was basically doomed once it was over the runway.
Mind you, I’m not trying to put the blame on anyone here, but to compare that crash with the recent MAX crashes is just not right. More comparable would be something like Qantas Flight 72, where the autopilot did in fact result in an uncommanded pitch down. Although the pilots recovered from that situation and the plane landed safely.
