The entire video is about what is going on at USAF Test Pilot School and worth watching. The F-16 stalls were particularly interesting

Sounds like an inertial-coupling departure - most high performance airplanes are susceptible when high roll rates are present with high AOA.When the A-7 first appeared in Vietnam, a few aircraft were lost to departures. This usually happened at roll in for a bombing run (Heavy load & high G) and were typically accompanied by very large yaw excursions. (It almost seemed that the aircraft swapped ends). Initially pilots were unfamiliar with the departure characteristics, but departure training was quickly introduced into the RAG training syllabus. Replacement pilots were taught to recognize incipient departure and prevent it or if departure occurs, the proper recovery procedure.
