Want to plug your second source admiralcloudberg as a brilliant blog that is worth reading if you're into airline crashes and system failures. He's very in depth and detailed in his writing

Thanks to your plug I started reading. Pretty good resource indeed.

I note that the accident report on the Turkish airplane further confirms what we have since learned about Boeing:

* persistent issues with radar altimiters in the entire fleet

* issue classed 'low priority', even if it feeds into autothrottle

* near-crash results in 'fix' that disables autothrotle if two sensors disagree.

* 'fix' is not rolled out to the entire fleet. And it is not 100% effective.

* issue is not mentioned in documentation, pilots can not see which sensor is used

Is it me, or is this exactly the same history as MCAS? Drives home the famous mantra "if it's a Boeing, I'm not going"
