"In the survey of the Parameter Recorder (FDR – Flight Data Recorder), obvious similarities were found between flight 302 of Ethiopian Airlines and flight 610 of Lion Air", whose accident off the coast of Indonesia 189 deadMinister Dagmawit Moges said at a press conference.

The information already had a first evidence based on satellite traces, findings known last week. US and Canadian regulators said there were similarities between the two Boeing 737 Max aircraft crashes.

According to early indications, the two aircraft could have been shot down for the same reason: the automatic malfunction of the system called MCAS.

Experts compared the profile of the two flights and found "parallels" in their trajectories and "variations" "exceed a threshold of similarity with regard to the possible causes of the accident in Ethiopia".

Aviation experts believe that the MCAS could have been activated on the flight from Ethiopia and could have contributed to the accident. And many scholars believe that during the tragedy of October, Indonesian pilots lost the battle against the MCAS.

Probably because of defective sensor readings, the automatic system pushed into the nose of the Indonesian aircraft. The pilots countered and again looked up, but they were canceled by the system. Each interval took about 15 to 20 seconds. This led to a series of variations of altitude until the pilots were crushed.

The public data of the Ethiopian flight are less clear and complete, but they seemed to show the same pattern.
