Edit: That said, there are no answers. It's just the long known story: A pilot ejects from a malfunctioning (but likely flyable) jet, gets cleared in the first two investigations because most other pilots would have interpreted the situation similarly, promoted, and then fired less than 4 months after moving with his family to the location of his new role. It remains unclear why but scapegoating to distract from the plane's issues is commonly seen as the most likely explanation, with all the risks it entails (pilots becoming more hesitant to eject or openly admit mistakes so safety can be improved).
