22? sounds like instant death to me... O.o
racing like that is racing on the edge of no return.
something comes loose... you cross that edge of no return.

i just wish they would build their own planes instead of f*cking up warbirds, and do it where nobody gets hurt, too.

well to be honest most of those warbirds were f-ed up already sometimes in 1946. Back then you could get them dime a dozen and immediately racing pilots started hot-rodding and modifying them. So it's not like they're wasting pristine airframes, these all have been in racing circles for quite a long time...

Sorry, but wrong... Kenny Bräck survived 214 g's (on his official homepage you can read the following sentences: ...my car caught air at 220 mph, got air borne and smashed straight into a massive steel pole in the catch fence. The impact was enormous, but leaving the cockpit intact. It recorded a record 214 g impact and left me seriously injured...)

@HG
 Yeah, somehow I too don't think any recovered & restored or ex museum bird is going to end up racing, or that hopefully the orignal removed parts from them ended up in said museum birds. Racing planes largely came from military mothball surplus & pre-tearing apart scrap salvaging, tech & parts suppliers, aero-workshops & rarer limited production batches of some universally rare componants.

@Wild
 A typo perhaps, 214, 21.4, g or G or say 214lb/kg-psi impact force (N)... If the speed is gradually raised/lowered at a paced rate, in say a cylotron bucket-seat arm thingy, some persons can withstand a lot of G - if it was a lamp post, anf he survived bouncing off it at 214 G and lived, the pole must have been writ off taking the beating instead.

Re: Kenny Brack's 214 G's - there is a difference when one suffers an instantaneous peak high G load which happens during car crashes and last only for a fraction of a second (often race car drivers suffer impacts of 70 - 100 G's and survive) and sustained high G loads like those in an airplane going out of control.

Even though Brack survived a peak 214 G crash, steady 16 G's applied for 1 minute will kill most humans.

  Hence why some modern jets/aircraft tend to have reclin-ed/able seats like F16 Falcon/Viper or be akin to the B&V's Assault Glider and a few early jets had some 'prone' pilot designs & prototypes like the Hs.132 & the 'Prone' Meteor repectively.
  To centeralise G force effects upon the blood system, with that being as perpendicular as possible to the said forces;

  I remember many years back in either Flypast or Aeroplane magazine, there being an article about the Prone Meteor, and its usage by the RAF Medical Establishments what it was like to fly and its ingenious 'escape' mechanism.
  The main problem with 'prones' is they require a lot more space management to fit in the laid out pilot & finer pilot vetting for acceptable height requirements.

Re: extreme G-forces survived by racecar drivers, besides Kenny Brack's 200+ G IndyCar crash at Texas motor Speedway there was also a monster crash suffered by Mark Blundell (also IndyCar) which some claim created even higher G-loads than the Brack wreck. In F1, David Purley survived - barely - 180 G in 1977 (deceleration from 110mph to 0 in about 2ft distance) and this is considered the highest G-force survived in F1 ever. More recently Robert Kubica's famous Canadian GP crash measured 75G causing only a mild concussion.

[Wildchild]

Yes, your correct. I was just stating that at 21 or 22 G's is not instant death, as shown wrong by F-1 drivers

Even then, extreme g-loads can be lethal if you decelerate suddenly, if you get slammed around, or if the g-forces are applied in the wrong direction. In those cases, the g-loads can literally tear you apart. Good article here:

  http://www.pbs.org/wgbh/nova/space/gravity-forces.html

For sustained g-loads, in addition to the gravity trying to squash you or rip you apart, there's also the problem of sustained GLOC. Without an adequate supply of oxygenated blood, the brain starts to suffer damage after just a few minutes, and after about 4 minutes most people will suffer serious brain damage. Likewise, the heart also suffers similar damage if its tissues are deprived of oxygen for more than a few minutes.

So, while race car drivers might suffer extreme g-loads for just a fraction of a second and survive due to state of the art safety systems, they're still damned lucky.

Well yeah, in most cases such extreme accidents cause multiple injuries, Brack had severely broken legs and a fractured spine and it took more than a year for him to recover.
