Findings from fatal Ethiopian Airlines' black boxes illustrate "catastrophic failure"

"Pitch up, pitch up!" one pilot declared to another before the cockpit radio went dead, per a Wall Street Journal report on Friday that chronicled the minutes from takeoff to nosedive of the Ethiopian Airlines Flight ET302, described with new details by people surrounding the ongoing investigations, pilots and airlines executives.

Details: The preliminary consensus deduced that an automated stall-prevention MCAS system activated due to invalid sensor inputs, pushing the nose of the plane downward per reports from data retrieved from the flight's black boxes.
