He pulled that radical, high-G turn in those last seconds because he realized his flight path was going to take him over a nuke storage area, which is a very big no-no.
It was the final flight of his career. His family was present to greet him when he landed.
At least he got the “final flight” part right.
Also, I believe the copilot was a squadron commander who listened to his troops and refused to allow any of them to fly with the PIC clown. So he flew instead. I think he “punched out” but he and his chute were caught in the fireball.
Hell of a way to go.
