The pilots turned the electrical power back on, which reengaged the stall-prevention feature, known as MCAS, and then used electrical switches to try to raise the nose, the Journal's sources said. It's not clear why Ethiopian Flight 302 pilots turned the automated system back on rather than continuing to follow Boeing's standard emergency steps. Ethiopian investigators are expected to release a preliminary report about the crash in coming days. The revised software will have two sensors, rather than one, and will give pilots more control over the system, according to Boeing. "We urge caution against speculating and drawing conclusions on the findings prior to the release of the flight data and the preliminary report," Boeing said in a statement responding to the report.
