Then, on March 10, 2019, Ethiopian Airlines Flight 302 - another Boeing 737 MAX 8 aircraft - crashed soon after takeoff from Addis Ababa Bole International Airport in Ethiopia. This is what we do at Boeing.

On Thursday, Boeing recognized the similarities between the two crashes, and acknowledged the role of its anti-stall system. "When the MAX returns to the skies, we've promised our airline customers and their passengers and crews that it will be as safe as any airplane ever to fly", Muilenburg said.

Before the Ethiopian Air crash, which killed 157 passengers and crew, Boeing had planned this year to increase total 737 production to 57 per month.

Muilenburg also said Thursday that the company was "sorry for the lives lost" in the 737 Max crashes.

A preliminary look at the crash report for Ethiopia Airlines flight 302, obtained by CNN, suggests that the pilots of the doomed airliner were absolutely powerless to keep the plane in the air, and it was Boeing's flight software that was to blame.

He said that the full details of what happened in both Lion Air and Ethiopian accidents would be issued by the government authorities in the final reports.

The latest decision comes the day after a preliminary report on the Ethiopian Airlines tragedy showed that the pilots of that plane performed all of the aircraft manufacturer's procedures, but were unable to control the jet before it crashed.

The arrangement may require the siblings to publicly forgive or absolve the killer in order to receive the massive payout. Riyadh has maintained that neither bin Salman nor King Salman knew of the operation to target Khashoggi last October.

The initial report, unveiled by Ethiopian Transport Minister Dagmawit Moges, cast further doubt on the system controlling the Boeing 737 Max 8 model, which has been grounded worldwide for nearly a month.

But when they turned off the system - as they were instructed to do by Boeing and the U.S. Federal Aviation Administration (FAA) in the wake of the Lion Air disaster - the nose was still pointed downward, leaving the jetliner vulnerable.

Most accidents take months of analysis because of the need to trace backwards to find a root cause from tangled evidence. As pilots have told us, the erroneous activation of the MCAS function can add to what is already a high-workload environment.

"Sadly, these two entirely preventable airline crashes demonstrate that the FAA is ill-equipped to oversee the aerospace industry and will downplay serious hazards and safety risks to the public rather than sound the alarm about safety concerns, problems, issues and hazards that pose substantial, probable, and/or foreseeable risks to human life", attorneys for Stumo said in the lawsuit. "We own it and we know how to do it", he said in a statement issued on Thursday.

The report from Ethiopia's Aircraft Accident Investigation Bureau spelled more bad news for Boeing, as it recommended that Boeing re-examine its Maneuvering Characteristics Augmentation System (MCAS).

A grand jury convened by US prosecutors last month subpoenaed a former Boeing engineer demanding he provide testimony and documents related to the 737 Max. That may not be surprising, given that Ethiopian Airlines had just five of the planes, including ET-AVJ. As a result, three motions of the stabilizer trim were recorded. "I think this is a more complex problem than what we initially thought".
