Hardly the point, but since you bring it up, even a momentary high G incident can cause unconsciousness. At least one of the prop trainers back when were notorious for this being capable of this.
Regardless, I was responding to the outrage of the other guy at the idea that they did not wear G-suits.
The most common aircraft for GLOC in the Navy has always been the primary training platform. Experience plays a huge factor in avoiding GlOC
so was i, but yes, i did forget a prop plane accident of such style.
I do recall that there were a few of those, for some not keeping track, at a few of the air races in Reno, in times past, too.
History discounts the fact that, during WW2, anything newer than a Grumman F4F, or a Curtiss P-40, started having a bit more speed and agility, which adds to more G-forces upon the pilots and airframes, too.
