Well done all you aviation warriors who clearly have no recollection of learning to fly. This "student" has zero muscle memory for what to do when things go wrong, his brain immediately fails to process the directional failure, he over controls massively and you can see him using the yolk like a steering wheel and pulling and pushing anything he can reach. This is not an infrequent occurrence, and it's the judgement call thousands of instructors make every day - is my student ready and if something goes wrong, what will they do? In this case the student failed to recognize and react to the problem correctly and was extremely fortunate to survive the outcome.
