Even if you've seen it before, it's worth another look...

Never seen the video - I'll love a ride in an F-18 or similar even if it did mean passing out - now to get the F-16 flying tonight in the sim.

Great find Charl. I thought he was just a typical American gum chewer, but oh no, it was 'ginger' flavoured. :P I'm surprised he didn't choke on it when he passed out!

And don't F-16 pilots wear pressure suits that stop the blood flowing to their heads? I've down aerobatics up to around 4G's and all I had to do was clench my muscles us. I thought it would be more intense in fighter aircraft!

The fighter jocks wear G-suits which constrict blood vessels in most of the extremities.
That way blood doesn't flow out of the brain as easily.
They also tense up (you would've heard the instruction to cross legs in the video) and grunt at high "g".
Most can withstand sustained 9g loads. (I would go out at 5 or so.)
F-16 drivers can pull higher "g" than most because their couch reclines, and the blood doesn't go rushing off to the feet as much.

Didn't you love the way he went out like a light, then came back and started talking where he'd left off?
Just like a Pause button.

Ages ago some chick got taken to Hungary (I think) to ride a Mig 29 on Who Dares Win (the one with Mike Whitney) and all she had to do was not to pass out to win something great. Unfortunately she passed out as soon as the plane took off! :D

Yeah AGSM(anti g straining) is the secret to sustaining high g a while back two of the programmers for FighterOps went on a T38 ride to learn about the aircraft they are modeling and one of them blacked out at fairly low g although prior to that he had used AGSM to go through 6 g as a warmup the reason why he blacked out was because of he didn't use AGSM. A g warmup is also required to sustain the higher g for longer periods g is also worse if slammed on suddenly compared to gradual application if its applied suddenly the g-loc is less than if its gradually applied.
