<div class="sreweekly-description">
|
|
<p>My coworker pointed me toward this article, and we had a really great conversation. I shared <a href="https://www.nytimes.com/2019/04/04/world/asia/ethiopia-crash-boeing.html">this</a> article that I’d linked previously here, and it hit me: Boeing (and the FAA?) assumed MCAS was fine because a failure in it would look like a normal kind of failure with an established recovery procedure.</p>
|
|
<p>The problem is, we’ve seen that the recovery procedure can fail if the plane is moving so fast toward the ground that the pilots can’t physically pull it out of a dive. And it seems possible that <em>no one knew</em> that the recovery mechanism had this fatal vulnerability. This has all the hallmarks of a classic complex failure.</p>
