 communicated clearly to pilots. There was no additional training. I'm trying to understand the relationship there from the C-suite down to the production floor. All of those things are accurate. And ironically, the MCAS system that Peter mentioned was supposed to be a secondary ancillary systems. The pilots weren't supposed to understand or even know when it kicked on. And therefore, the Boeing decided you didn't need to tell them about it and you didn't need to train them in the simulators.
