Automation won't kill you because it makes a mistake, because it's gone nuts, because it feels suicidal or it's just having a real bad day. Automation will kill you because someone got the design...

To my mind the materials testing (although there are still a lot of questions in that area) wasn't the biggest issue with Grenfell. The real problem was grafting new-standard-stuff onto...

But the wings were correctly designed. The engines were designed too large, or undercarriage designed too short - take your pick.

They had to extend the nose gear for all Max and design and...

Depends what you consider a "long time" - from the details we have they appear to have diagnosed a stab trim problem and hit the cutouts within 40sec, which is a lot quicker than I recall in e.g....

According to the report they were turning back when the final LOC happened (and they certainly returned to land...). Lion air were also returning when they crashed. Coincidence? - probably, but I...

If we're looking at statistics, might I suggest the 737-NG as the cure ?

Pretty much the same aircraft as the MAX, same type rating, no extra flight crew training required, about same price,...

The greybeards may have another reason - in the "old" days it was specifically advised not to use main electric trim to counter a runaway.

It neatly dovetails with some of Dennis Tajer's words that struck me in the 60...

Not only that, it already existed (albeit for slightly different design purpose) on the KC-46. All they had to do was rip it off there, remove the redundant AOA inputs and make it just work off one...
