Gentlemen,
He pulled 6.5 G's for a couple seconds and 5 G's for quite a while. Above 4 G's the blood pressure in your head drops close to zero and it is zero above 6 G's. The eyes take more blood pressure to function than the brain so you lose vision first and within seconds you lose consciousness. During my airshow days I have GLOC'd twice going completely to sleep and almost killing myself both times. Modern akro planes like the ones you see in the Red Bull races can pull 12 G's and a pilot can operate like that for only 4 seconds before the lights go out. So extremely high G turns and maneuvers must be completed quickly. Just 4 G's will put most people to sleep if you pull it for 30 seconds so the wall of death ride is super dangerous. It's really hard to tell when you are going to black out.
