Lion 737 Max 8 'un-airworthy' in flight prior to crash

Investigators have called on Lion Air to improve its safety culture, after a probe into the loss of its Boeing 737 Max 8 found that pilots on the flight directly prior to the crash had continued a journey even though the aircraft was in an un-airworthy condition. That 28 October flight from Denpasar to Jakarta had experienced similar technical issues to the doomed flight a day later. Shortly after take-off, an indicated air speed disagreement message appeared on the primary flight display. The aircraft’s stick shaker was activated and remained active throughout the flight.
