Hi Deanna

In modern fighters like the F-15 or the F-16 you are exposed to up to 9 g's. This happens fx. when you want to make a sharp turn in a dogfight or during aerobatics. If you were sitting on a scale while pulling 9 g's, it would show 9 times what you weigh. This also means that everything inside your body weighs 9 times as much. This is especially a problem with the blood in your head since it wants to flow downwards. You can resist this by tightening your muscles and by wearing a g-suit that squeezes your legs, stomach and in some cases chest and arms to prevent the blood to flow there. If you don't you will first loose your vision & then you will pass out due to lack of blood (oxygen) in your brain.

[I've obviously never flown in a fighter or any other aircraft. I just had some basic questions about the g force and what it does to you. I read an article about these new suits that are being developed and I basically wanted to know what the effect of being in an F-15 or the such would have on your body. ]
