OK, you got me. I’m not a pilot. 3,000+ hours. B-47. Master Navigator. 15 years in R&D. My use of the term “high speed stall” was from conversations with flight test pilots. As they described it, it wasn’t a complete stall, but a loss of lift due to high angle of attack and induced drag. They also used the term “mushing” for nose-up loss of altitude during pull-out from a dive. I remember it was a problem in the F-105.

Don't worry about them, you're correct. It's actually called an "accelerated stall", and every flight student learns about it. The term refers to a stall caused by an abrupt pitch change that causes the wing to exceed its critical angle of attack, even though the aircraft is flying well above stall speed. An aircraft can stall at any speed if the critical angle of attack is exceeded.

Anyone with any knowledge of aerodynamics should know this. It's very basic. That said, I don't know if this is what happened in this case as I have not viewed the video yet.

I get it.

I see where you are coming from now. Those that have not flown and have no clue why an aircraft flies, one must keep the terms basic, as in stall, meaning separation of airflow from the wing equals loss of lift. Accelerated stall is the same thing, but associated with abrupt change in the relative wind to the airfoil, can happen at any speed, and the abrupt change separates the airflow but well above “normal” straight and level 1-G slow speed flight.

The Thud. . .hmmmm. . . .just how OLD are you?

Hah.
