G-LOC (gravity induced loss of consciousness) from Radiolab
« on: November 23, 2013, 02:37:35 PM »
According to this story from Radiolab, we experience about 2 Gs on a roller coaster.   Fighter Pilots experiencing over 10 Gs to 12 Gs, where a 200 pound man weighs 2500 lbs, about like a car, experience some weird things.   The brain loses blood, and being unable to understand, it compensates by filling in the gaps until the blood returns.  Some pilots climb out of the cockpit and comfortably sit on the wing, looking in and seeing themselves flying the plane.

The out of body experience and the tunnel with light at the end are typical.

Damn, that is one big...whatever it is.  Daily Show would have fun with the visual.  Always have said those end of life visuals people see is the brain shutting down and chemicals going haywire.
Yo, put that in your pipe and smoke it.  Quit ragging on my Lord.

Fighter pilots that pull G's do so with several tools to help them do so: G-suits, reclined cockpit seats, and a diaphragm "grunt" technique, all to help keep blood in the upper body. Pilots need to anticipate G onset and begin the gunt as increasing G's are pulled. Getting behind the onset and grunt are when pilots get in trouble and grey- or black-out as blood is pulled into their legs.[1]
 1. I flew the T-38 in USAF pilot training, regularly pulling up to 6 Gs.
