That said, the previous crew had dealt with it successfully despite (probably) having no idea about MCAS. They identified the issue as a runaway stabiliser and dealt with it accordingly. Even though they wrote it up as STS running reverse, it did give the airline / accident crew advanced warning of stabiliser issues on the aircraft and how to resolve them. We are of course still speculating on what briefing the accident crew received concerning the flight control issues from the previous sector and what had been done to rectify them in the interim.
