No, the slow high-G blackout is due to gradual blood starvation. In
modern jet fighters, which can achieve high Gs much more abruptly than the
older ones (or the centrifuges), it happens exactly as I described:
sudden unconsciousness without the slightest warning, due to a total
cutoff of oxygen to the brain. This phenomenon, called G-LOC (G-induced
Loss Of Consciousness), was only recognized in the last 10-15 years. It
killed a number of pilots before it was understood; the pilots were
*expecting* a few seconds of warning, and didn't get it. (Worse, the
recovery of consciousness is slow and there is a period of grogginess and
