The vid of the 737 simulator replicating the "extreme mis-trim" scenario described in the Seattle Times article above has been taken down apparently, in googling around for it I found this:

ET302 used the Cut-Out switches to stop MCAS
By Bjorn Fehrm
Note: The article offered a Video as an example of the effects of not trimming to neutral before hitting Cut-Off. After reviewing the effects of the video in the context of the article, MentourPilot decided we should leave the text but not include the video any longer. MentourPilot’s YouTube channel is an independent initiative to offer the public correct and positive information of all the work which is behind their safe travel in the skies. In the sensitive situation of an ongoing investigation of the crash of ET302, where not all facts are on the table, he concluded after discussing the impression the video left with a colleague, it was not in line with his intent of setting up the channel. In the haste of the change we took this as his company not wanting the video aired, it was not. As facts in the ET302 case comes forward we will discuss with MentourPilot if this situation changes.
