Indy car CRASH [Highest G-force ever!]

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...)

These losers cant drive i mean how can u crash while driving on such an easy track

@jonathanstensberg "214g against a wall would be fatal, but this isn't a wall."

Correct, which is why I say that the reading is not valid for the whole vehicle. Only a small part of it hit the pole and that's probably where the Tapley meter was.

Thanks for keeping your cool. Sorry if I was a bit short with you earlier on. YouTube can be a bit like that sometimes.

@jonathanstensberg "your not understanding the profound shortness of the 214. the brain does not have time to move(much) in that short of a time."

I'd suggest you look at Newton's First Law for an explanation of this and why it is so dangerous. Skull stops, brain keeps moving. Damage is the only possible outcome for the same reason the car is damaged. One part of the car stops against the pole while the rest keeps moving, thus destroying it.

@jonathanstensberg "g is g" There is G and there is G onset. This is a major issue for fighter pilots in relation to G-LOC, which is not an issue of sustained G but one of onset. The onset in this case it massive - much higher than that for a fighter jet and the total is also way higher.

@jonathanstensberg "there is no exact g that causes death."

Couldn't agree more but there is a point at which survivability becomes a matter of probability. Certainly the structure of the vehicle and the security of the driver play a big part in increasing that level of probability. Helmets, HANS devices, Snug cockpits, seatbelt, deformable structures etc all play a part but there is a point where it actually starts to work against survival.

@Camerameister1 my apologies, its the front coming around, not the rear. and second, what deceleration problem? finally, yes, 214g against a wall would be fatal, but this isn't a wall.

[jonathanstensberg]

@Camerameister1 g is g. this isn't a jerk measurement which is g/second or m/sss. there are two basic g experiences, the kind you feel when turning in a car and the kind when you fall to the ground. your not understanding the profound shortness of the 214. the brain does not have time to move(much) in that short of a time. 214 is a huge impact but its a short impact partially nullified by the following motions. if he hits a wall head-on, he's dead, no question, because nothing else happens.

[jonathanstensberg]

@Camerameister1 very well put. the final thing to say is that there is no exact g that causes death. some people will survive 50g while another could die from 15. this guy just happened to have a century of high speed crash-engineering behind him to save him from 214g. that's not to say someone else in a similar crash could die on impact. kenny brack lived through a recorded 214g crash. i'm out.

@ACfireandiceDC Yes. I actually think that the bit where the Tapley meter was is probably what came into contact with the pole. Alternatively, it may have come loose. Originally I thought the reading was probably false - I don't know how it could be reliably measured at such an impact - but now I think it's possible. I just don't buy the idea that it's true for the whole car and driver.

This may not have been 214g's. The g-force-recording instruments may have been on a different part of the car than he was in.
