So is it not bureaucracy that led us here? I know Boeing will cop a lot of flak for this but it seems to me that unless they wanted to spring for a whole new type certification, they instead had to build a computerised system that adjusted the slightly changed flight profile to be more like the old flight profile.
So now we have old systems with new computers that make them act like their older selves, but that then negates the need for pilots to understand the new system (otherwise what is the point of it? I get that anti-stall augmentation is to improve safety but training pilots would do a lot better, it seems).
I am not trying to get ahead of the investigation, I feel we have done that already, but with the aircraft grounded across most of the world surely regardless of the outcome we need to do better in the future. This will be a very costly exercise in an industry with thin margins, if it doesn't highlight the structural failures rather than blaming it on an aircraft manufacturer, it was all for what?
