Gnandengurg....here's one that some on this forum will remember very well. What is not mentioned in the report is the altitude at which this asymmetric "exercise" was initiated and thereby leaving absolutely no chance for recovery, even with the "best of intentions".
Airforce training was very thorough in my day and I assume this is still the case but still this can happen out of the blue . Likewise long GA experience teaches common sense and self-preservation. What we do today however, (or more precisely, what we don't do today), in my view, really pushes the envelope with the actuaries.
