bull shit. 26 times the nose went down. You want to try it?
The nose went down 26 times because the pilots were incompetent and didn’t disable the automatic trim.
Sorry, Moon man is right and you are full of.... So the plane’s nose dipped 26 times .. It would have dipped 27 times except the pilot ran out of altitude and ideas at the same time. The first time the nose dipped, ANY competent pilot would have flipped a couple of switches and thought nothing of it, just a glitch.
These are the “Stab trim cutout switches” that Media is referring to everywhere.
They form part of the “Runaway stabilizer” memory items that will stop most unwanted movements of the stabilizer, including the mentioned MCAS system.

It’s Ok: He probably owns Boeing stock as well (he’s a Musk cheerleader).
He’s dumb as a rock on this one, too. MCAS was an add-on system which intervenes in normal flight in the critical moments immediately after takeoff. There is no excuse for Boeing to have utilized a single sensor for its input when a fault can cause a departure from flight with critically-short reaction time (40 seconds). Training is one thing, but anyone with half a brain who reads how the system operates can see that MCAS was added haphazardly.
The overarching question is “Why?”
What incident during flight testing could possibly have prodded them to butcher a well-designed flight control system with an add-on?
Better, how did it get certified without thorough testing?
There’s no other tangible explanation for this other than they found a defect in flight handling for which the risk was sufficient to patch the system but deemed too expensive to redesign the flight control system.
Other than the obvious critique of failing to design a safe fix, the root of this is lousy engineering. I can’t imagine how this might have occurred, but the fact is that the 737 MAX 8 was not an all-new aircraft: With all the design changes it should have prompted a very strict certification process rather than the fast-tracking it obviously received for being an existing/updated model.
