This really isn't good for Boeing. We flew on a Southwest 737 MAX 800 last month, nice plane. Lion Air is a terrible airline, but the crash may not be their fault.
I'm more of an Airbus guy...better planes.

Doomed Lion Air Flight Had Dangerous System That Boeing Didn’t Tell Pilots About
One erroneous signal could have triggered fatal dive according to expert reporting—in a system introduced to the new 737 MAX without the knowledge of any pilots.

Pilots flying more than 200 of the new Boeing 737 MAX-8 jets were unaware of a potentially deadly flaw in the flight controls – including the pilots of Lion Air Flight 610 that crashed in the Java Sea killing 189 people.
Aviation Week in a story by three of its most expert correspondents reveals that a system unique to the latest model 737 could, without any input from the pilots, force the jet’s nose to suddenly dip, potentially triggering a steep dive – exactly what happened in the Lion Air crash.
Responding to the report, Boeing told the Seattle Times: “We are taking every measure to fully understand all aspects of this incident, working closely with the investigation team and all the regulatory authorities involved. We are confident of the safety of the 737 MAX. Safety remains our top priority.”
The system, called Maneuvering Characteristics Augmentation System (MCAS) does not appear in the flight operations manual that pilots use to become familiar with a new model – nor, according to the Aviation Week report, was it revealed to pilots as they underwent training to convert from older model 737s, which began service in the 1960s.
MCAS is unique to the MAX versions of the 737. It is unheard of for pilots who move from one generation of a jet to another not to be alerted to any change that has critical bearing on controlling the jet.
The sequence of events that could have been responsible for the death dive of the Lion Air 737 is clearly suggested by the Aviation Week reporters.
