He might have been. Certainly it depends on whether he as in stall, as it appears, and if so, how deeply. It also seems he may have had dual engine failure which would have caused his controls to fail as well. All the fighters ones have a certain rated performance based on their velocity. When I flew they had what they called a zero-zero ejection seat. This means they could survive a zero velocity, zero altitude ejection. However, in a stall, vertical velocity can be considerably negative so to survive, the vector produced by the seat's velocity and whatever forward velocity remains must exceed whatever negative velocity is occurring. Also here there was a rotation and the pilot ejected near 90 degrees so that offset much of the seats velocity. So bottom line, he probably was lucky. Amazing video as well.
