Yet it is still Boeing's refusal to assure that the requisite information ended up in front of the pilots. The manual must be sold with the plane and it must be accurate, containing enough information to instill in an average pilot an accurate understanding of all safety critical aircraft systems, which MCAS, through Boeing's failure to reclassify during certification, wasn't acknowledged to be.

Boeing doesn't get a pass, and the Ethiopian Air pilot was just as capable if only a bit less informed.

If you cannot safely deploy your product/documentation, then you aren't done. Boeing should have known and recognized that.

The certification process is meant to be proof against a failure like this, which goes to show that there are deeper problems in the organization that need remediation.
