AKA a stall turn

OK. First time I've heard it called that.

Looking at the fly-imaa.org article you cited, "stall turn" is another name for
a hammerhead stall (a term with which I'm familiar). Note that in a hammerhead,
the airplane should NOT go to 0 forward airspeed -- it needs airspeed to
maintain controllability. To wit, " The second thing that can cause a flop
over, especially in trainers or slow planes, is not enough speed when you put in
the rudder." (from that article). So, the airplane does NOT "stand still in
air" per the OP's question. It only appears to stand still. Admittedly, some
aerobats do tail-slide maneuvers, during which the airplane will briefly pass
through 0 airspeed.
