Excellent post Centaurus! I think you, FGD135 and 4dogs have all hit the nail on the head i.e. the loss of older, wiser heads and in particular instructors!
Too many times I have been witness to overzealous ATO/Checkies who think they are re-inventing the wheel. However they all seem to lack knowledge/experience in the basics of physics i.e. what keeps the blue bit up top!
Examples of shoving the power lever back to the flight idle stop on rotation or killing the inside engine while in the middle of a reversal turn, all come to mind.
All of this seems to come back to a lack of good basic initial training and the product these flying school factories are putting out!
