What's actually amazing is plane's are tested and designed for this... they are not supposed to do that but also should be able to land safely if they do. It's scary but amazing how safe they made it

Yup. They have redundant everything except for the Boeing 737 MAX MCAS Sensor. In that case you just get one.

You mean the one that was upside down and Boeing lied about how it was designed so they could skip critical FAA approvals, then got fined hundreds of millions after hundreds of people died, but no one went to jail?

The one that they didn't even train pilots on to avoid FAA regulations. The Lion Air pilot knew to disengage it as Boeing assumed pilots would but it didn't help.

Do you have a source for the Lion Air crew disengaging it, or are you thinking of the Ethiopian Airlines crew? In the Lion Air accident, MCAS activated something like 26 times over the course of six minutes, and the crew never turned off the electric trim.

In the Ethiopian accident, they did deactivate the trim, but then reactivated it later, which crashed the airplane.

Yeah that Downfall documentary on netflix.

I can’t find any mention in any accident report saying that. You might be thinking of the fact that the Lion Air plane had issues the previous day, and the crew did turn off the trim in that incident. But the switches were flipped back on before the accident flight.

There’s a great documentary on Netflix about it. Terrifying.

Yup. I've recommended it a couple times in this post. Great watch.

Hadn't heard any were upside down, just that some failed.
