I love Aviation Safety, and actually read it. The May 2021 article, “Moose Stalls,” echoes a difficulty also seen in soaring, the stall-spin in the turn from base to final, where the glider is closest to the ground.
Your box on page 5, “Steep Turns, Low To The Ground,” implies that the danger is angle of bank. While stall speed increases with bank angle, a steep bank actually decreases the risk of a spin. There is a greater risk of spinning with a shallow bank close to the ground. This is pretty well understood in soaring. Here’s the mechanism:
