To show the difficulties associated with the maneuver and what can go wrong when it is not properly performed, John starts by mentioning a recent accident involving a Learjet performing the maneuver and includes several excerpts from accident reports covering the incident. He then proceeds to give step by step instructions and tips for performing the maneuver and for minimizing the risks involved.
However at the end of the entry, John concludes by saying that if you end up missing your approach the first time around, you might just be better off landing at your alternative airport choice rather than risk a second approach as second approaches also entail risks. Good advice worth heeding.
