BB beats the incompetent third world pilot drum at every opportunity.
If these accidents were the result of mere pilot error, or poor training at one or two airlines, the entire world fleet would not be grounded.
Rather, pilots at the guilty airlines would be grounded until they retrained, while it would be ops normal elsewhere.
That said, I would not fly with Lion Air, but only because of their long history of accidents where the crew clearly were at fault. Others in the know claim that Ethiopian’s standards are actually quite good.
