The Lion Air flight JT 610 had taken off from Jakarta on 29 October and was expected to arrive at its destination at Depati Amir airport in Pangkal Pinang an hour later but it crashed into the sea.

American Airlines Group Inc said on Wednesday it was "unaware" of some functions of an anti-stall system on Boeing Co's 737 MAX until last week. She said: "'We were supposed to do this together, there's supposed to be Rio here.' And she cried - all of us cried too". "Safety remains our top priority and is a core value for everyone at Boeing", the company said.
The Journal also reported on Tuesday that when Boeing made a decision to install the flight-control feature, the company determined that it was fail-proof because it was impossible for the combination of sensor failure, pilot actions, and automated nose-down commands to cause any serious safety hazards. Pilots speaking with the outlet claim they weren't properly trained on the safety feature, which automatically adjusts an aircraft's nose downward in the event of disturbance.
On the Pilots of America online forum, an American Airlines pilot posted an informational bulletin from a pilot's association and added this: "We had NO idea that this MCAS even existed".
Known as the Maneuvering Characteristics Augmentation System, it was added "to compensate for some unique aircraft handling characteristics", according to a bulletin sent by Southwest's flight operations division to its pilots on November 10.
