And then a second crash occurred where they followed Boeing's procedure, it didn't work, were forced to diverge and then crashed.

Boeing's procedure only works if you catch it quickly. If you let MCAS trim the aircraft too much it is difficult to recover, particularly at low altitude.

That's how it seems.

1. Both stab trim cut switches now cut electronic horizontal stabilizer trim control and automated control together.

2. And manual control does not function at high airspeeds.

3. So... A planeload of people is screwed...

That seems like a really risky set of design choices.
