Sorry, I am just a worker-bee. No VIP Invites for me. If I had that kind of clout I would be on the Roadster Forums, not the Model S Forums.
But I do read accident investigations, and this is as far off-topic as I care to go into such a tragedy with a non-pilot:
For if you were a pilot (and Germany has produced some of the worlds finest pilots dating back to Otto Lillienthal, so you would know this) there is still this thing called "airmanship". When the the automation is doing something un-commanded, the well-trained pilot turns it all off and flies the airplane - by hand. Using airmanship and principles of aerodynamics.
Such as "in a stabilzer trim runaway at 500 knots
and the thrust levers still in the take-off position, there is too much air-loading on the horizontal stabilizer to control - reduce thrust and speed immediately". And maybe - just maybe - in clear weather looking outside when the instruments don't make sense?
BTW, 500 knots IAS (indicated airspeed) is 160 knots
over the red-line (maximum certificated) speed of a 737. Since a 737 does not accelerate as quickly as a Model S, that took some time to reach that state of affairs.
And that is exactly the state of things when Ethiopian contacted the ground and made a 50 foot crater into the ground (that would be 16 meters auf Metric).
Runaway Stabilizer Trim used to be a Memory Item for most of the worlds airlines. And the Very Second thing on that Memory Item List can be summarized for the layman as "Turn off the Automation".
Thanks to the hubris of "software engineers know better than pilots" it is once again a required Memory Item - for most carriers.
And to as your ill-advised comment that the operators being "decently capable" - the first officer of the Ethiopian plane had just 200 hours time - apparently much of that was simulator, not in an actual airplane. In the United States, he would be barely qualified for the most minimally paying single-pilot single-engine flying job (something like towing banners), let alone flying a major airline passenger jet.
Good Day Sir. Next time,
