Trish,
While admittedly this is an area of interesting research I too think that a clear understanding of some of the terminology is required.
“Loss of control” to a layperson is understood by the terms of reference that they have at their disposal. Another is the phrase “the aircraft stalled” also pretty much universally misunderstood by the media and general public. I would invite you to sit down with some folks in your area who have a solid aviation background to impart some of their knowledge to you. This will allow you to gain a better understanding of some of the material.
As for upset training, I know of a number of operators that are providing this. In our case, we have been providing annual upset training to our flight crews since 1986. It’s as you suggest, another valuable tool in the knowledge/skill base of flight crews.
Best of luck in your continued research.
