Poor guy - he must have been exacerbated
What IS exasperating, is this:
The instructor returned to the aircraft and confirmed with the pilot that he was still happy to undertake a flight on his own.
The pilot thought he was going to roll the aircraft, then spun it through more incompetence, then unsurprisingly admitted he was 'shaken' as he'd then impacted the ground so hard he bent the tail. I wonder what it was that gave the instructor the confidence to believe the pilot was safe to fly away on his own
Perhaps a refresher lesson in the office over a strong coffee, some supervised practice and an inspection of the aircraft would have been prudent
