 Yep, yeah, so they give you the technique, you know, basically tightening up your legs and your core to try to force the blood back up into your head when you're under G, and then the HIC maneuver, the breathing that you have to go through to try to maintain some breath in your lungs. So we had a briefing prior to the flight where they go over all that and some of the safety stuff, obviously, with the aircraft.
