In march 2019, a second boeing 737 aircraft crashed in Ethiopia. Here were 157 people killed.

A report has shown that inadequate pilottræning and errors in the aircraft's software was to blame in the crash in Ethiopia.

the Error was in the system, MCAS, which should prevent the so-called grayling. It occurs when a plane loses buoyancy due to poor speed. It causes the aircraft's nose to turn upwards. But grayling should be immediately prevented, for the plane not to crash.
