So what was the reason? I don’t feel like watching a damned video when 50 words is sufficient.
Video is actually pretty good. They do a good job of explaining what they believe the problem to be.
Your loss. The video isn’t long, about 7 minutes.
I’m with you. I can read 500 words of text faster than a video presenter can speak 500 words at a spead you can hear and understand every word.
Plane is too low to the ground for its larger engines, so they raised the engines slightly above the wings, which makes the plane want to go nose-up. Software is supposed to correct that by pushing the nose down, but at takeoff the nose should go up.
The 8,000 hour Ethiopian Airlines Captain forgot to turn off the autothrottles when they started having problems with MCAS. All attempts to fix the stabilizer trim were thus attempted at takeoff power. Therefore, even though they did try to do the right thing and switch to manual, they were unable to control the stabilizer trim manually due to the plane traveling at 500 mph. They turned the autopilot back on to try to get back some control and used the yoke switch to cut off MCAS...for nine seconds, as designed. Whereupon the crew apparently lost concentration due to the crisis, MCAS came back on, it used the faulty sensor reading that had started the problems, and it dived the plane straight into the ground - still at full power.
Poor software design by Boeing, but the genesis of the accident was a boneheaded mistake by the flight crew that it is hard to imagine any American airline crew making. There is going to be a lot of finger pointing.
A picture is worth a 1,000 words. A video is worth 10,000. if you are expecting an explanation in 50 words, you will get 0.5% of what this 5 minute video gives you.
Exactly
