Recommend you guys don't go crucifying the crew from a flight discipline angle without knowing all the facts. "Hearing" that a maneuver is prohibited, or believing that a crew was not qualified to do something, and then all of the finger-pointing, "I-wouldn'ta-done-thats", and armchair courtrooming that goes with it is a bunch of crap....especially when the known facts don't yet support it. It doesn't frankly do anyone any good, except perhaps to satisfy some folks' innner superiority-complex-fueled need to point out someone else that appears to be doing something wrong (no different than the mindset of the uniform infraction zealots just waiting to pounce on the next untucked PT shirt or sunglasses on someone's nugget).
Using Bud Holland videos as an example of poor airmanship and lack of flight discipline, and the disastrous potential consequences of those attitudes and actions, is excellent, because he is a well established, well researched case of it.
I'd reserve snap judgment (and use of it as another example of poor airmanship and lack of flight discipline) on others, like this Apache video, until the actual facts are known.
If it's eventually determined that they were in the wrong, then cleared hot. Until then, master arm safe to prevent frat.
