For an instructor to do what he did in a flight test under simulated conditions would he have passed his flight test.
Yes they were lucky but from my opinion he could have done better, given he never committed to the landing as he was pumping throttle all the way to the ground almost, what if engine came back and he was close and flew it in to ground because of momentum.
I would be hoping the instructor get remediatl training as he was very lucky not skilled.
