This is a pretty sad article. I wonder if they've ever considered g-suits to mitigate the pressure on the body. I'm not sure if it'd be effective but fighter pilots have a pretty similar set of extremes that they work in.
I was thinking along the lines that putting high G pressure on your circulatory system is probably putting a lot of stress on the brain that otherwise wound be there. The sled head they talk about seems like it's almost mild hypooxia or something.
