As this thread is about FAA oversight, based on the in-house communication of Boeing employees, the language used indicates great frustration at the working level about decision made of higher management level, and the hope that the FAA would put an end to it, which it did not. The major missteps already identified, which FAA was not fully informed of - or has inexplicably allowed, in simple language are:
1. MCAS was decided as not necessary to be known to pilots.
2. The expansion of power of MCAS after the initial design of a more "benign" form
3. One sensor suffices for MCAS purposes
4. No simulator time needed.
The employees having those conversations should be immediately protected from their (former?) employer and given whistleblower status to be able to identify who their higher ups were for those fatal decision....
