Relating to the question of why the plug opened on this particular flight an not any of the earlier ones:

There is a huge difference between a sensor temporarily failing with the pilot making completely unwarranted inputs commanding the plane into a stall, versus a system that actively and repeatedly...

This seems consistent with the videos explaining it, but it immediately raises the questions:

Why is the plug door, which is never meant to be opened, designed such that it can be raised out of...

Interesting that the one incident involved a DVD player, not a cell phone. Seems the problem is not wireless transmission on a dedicated band, but just general RF interference from the electronics....

Whether the cabin video is fake, I cannot say for sure, but some of the "analysis" "proving" it's fake is quite sad.

I'll pick one post to respond to, but it's one among many.

That was listed as a sub-step of the disable autopilot step. It didn't have its own number. If you were already flying manually when the runaway started, you'd skip that. The clear intent of the...

I remember reading the threads from before ET302, when JT610 was still the main topic and MCAS was just becoming known.

The advice given then was: "You see the trim is running away. All you do is...

Speaking as a passenger whose first reaction to that video was, "cool!", what is the problem everyone else seems to understand? Is it the strain on the landing gear? Is it the fact that they...

No need to pile on Fly Aiprt. True, coding Java isn't really comparable to real-time systems in assembler (something I haven't done, either) but the very valid point stands:

Yes, that is right. A few months ago, a poster who seemed to have a lot of insider knowledge of MCAS explained its workings. Everything he said appears to have been correct.

That's easy: MCAS will not input multiple trim commands unless it is reset. Tugging on the manual trim wheel, successfully or not, won't do that. It is reset by the use of MET (among other possible...

This checklist assumes that at least one of the pitch trim systems will function normally. The steps are to figure out which one is the good one.
