There may be some days when my butt might be in my brain but I've
never had it the other way around, Dan. I can see it's a lot less
stressful to take G's sitting with the extra weight down your spine
than it is prone with the weigh of your head leveraging on your spine.

3.5 G's is like putting some 60+ lbs. of weights on a 25 lb. head.
You must have the neck of the CA governor or an extra rope to your
helmet from the hang loops to support those G's. Holding a 60 lb.
cement bag over your head while sitting might be easier.

Just a few more thoughts,

I pull the same G's in HG as in gliders on a regular basis, up to
about 3.5. The body will take much more G prone than sitting, unless
your brain is in your butt. G induced LOC happens because the blood
leaves the head. The problem with prone is having to hold your head up
all day. Sitting up is an inferior position for pulling G's, but it's
alot more comfortable.

Evolution is a slow process, but when you get it sorted out, you will
find out why it's a superior position. I initially crossed over to
sailplane because of back problems, and Im glad we don't fly them
prone.

Im quite aware of that effect, JJ, looking down & to the right during
a left turn is supposed to cause vertigo, suprisingly I've never
experianced anything like that, even doing aerobatics prone. Must be
physiologically different when flying on your belly like a reptile, as
I've never heard of anyone get that effect while hang gliding.
