What a lovely read. A number of Captains who taught me how to do proper energy management and thrust idle descents had learnt their craft in the 727. It was awesome to learn it from them and something I prided myself on in the jet.
It was a great shame that once I started to get my own first officers, a lot had very little interest in actually learning the lost art of energy management and they never understood the best techniques and procedures for flying the jet. Frustrated me to no end.
