This accident makes a case for increased training, if anything. Had the crew been better trained, this would've been nothing more than a go around. No paperwork required.
Self evident.
But you're missing my point completely.
Look deeper into what is trained and why, and how much of it is really essential or useful.
Are exams on dry adiabatic lapse rates or precession in a magnetic conpass either necessary ot relevant? Who really needs to understand the errors in an IVSI or why a third sector climb rate is critical?
And how well evidently numerous reasonably capable people around the world seem able to get along for whole careers without it.
