To be really specific for those not aware, pilots need to do special breathing routines when under high g-forces. Deep, rapid breaths. They need to suck oxygen into their body as quickly and efficiently as possible to maintain consciousness, because the g-forces forces blood away from their heads and towards their legs and feet. Here's a "classic" video of a pilot successfully evading an unbelievable number of SAMs over Iraq. The rapid breathing might make you think he's panicking. Nope, he's got it 100% under control and is following training perfectly. Though I'm sure he certainly needed a drink after making it home. https://www.youtube.com/watch?v=qUjX1RntqVw https://www.youtube.com/watch?v=qUjX1RntqVw There's also sort of a method of flexing their thighs that they learn. Restricts blood flow to the legs, so there's more blood for the rest of the body. That's a bit of an athletic endeavor in and of itself. Try flexing your thighs... now hold them that way for 5, 10, 20 minutes. Yikes. Anyway, how the hell could you even bark out voice commands while doing that sort of breathing!?!?
