One thing I've been wondering: somehow the pilots were able to bring the nose back up... it was only (apparently) after multiple nose downs that they eventually failed to recover the plane. What was going on there? It's as if they understood how to correct the stabilizer trim, but weren't aware of the cut-off switches.

My understanding is that every time the MCAS activated, its effect was incremental. It could command only a limited deflection of the relevant control surface each time -- less than 1 degree? -- but the cumulative effect of multiple activations would eventually exceed the ability of the manual controls to override it.

From the reports I've read it was 2.5 degrees, even though Boeing had produced safety docs to the FAA only mentioning their initial design when they were only applying 0.6 degrees per activation.
