For those who are blaming the airlines, maintenance department and pilots for crashing the MAX, I have one question:
Why are those people perfectly able not to kill hundreds of people within a few months with the 737NG?
Good question. But..
ET lost a 737NG back in 2010 off Beirut, to which the probable cause was described by Lebanese authorities to be "the flight crew's mismanagement of the aircraft's speed, altitude, headings and attitude through inconsistent flight control inputs resulting in a loss of control and their failure to abide by CRM". The airline obviously refutes the conclusion.
As for JT, they did write off a 737NG within two months of delivery back in 2013, luckily without any fatalities. Not to mention several other incidents throughout the years right up until JT610,
Granted the NG accidents weren't consecutively. But that's just the luck of the draw to be honest.
