Well done to the pilot for his recovery. Now the instructor who signed him out and the flying school need a long hard look at there operation.
Maybe shut all flying schools down and start again. And sack all CASA FOI's and start again. I know I'm dreaming.
Increase experience levels for instructors and pay levels and get career instructors and retired pilots to come back and put there experience back into the industry.
Now ducking for cover lol
