Seems that lots of people here think that practicing glide approaches (with the engine throttled back to idle) and then doing the same thing, with a genuine engine failure, will enable them to reach the airfield on that awful day.....have they never witnessed the difference in the gliding performance of an aircraft with an engine throttled back, as opposed to a genuine "deadstick" engine???? Guess not.
Regarding "the Shock cooling, more folklore" well Chuck you are right ....its beyond help!!
