It’s my understanding that the pilot had no culpability in the crash. The fighter lost all engine power. There’s nothing the guy can do when that happens.
I don't know the specifics, but from my understanding most modern fighters are virtually uncontrollable once they've lost all power. The good ol’ days of control cables are gone, replaced by hydraulic systems that require power to operate.
God bless Mr. Yoon and the pilot. Each has his specific needs in the aftermath of this.
