"TMS president Eddie Gossage said he was "very pleased" with the fence's performance. Nothing of any size reached the grandstands, and the fence did not grab the car and stop it suddenly, a situation that likely would have caused internal injuries."
200 Gs sounds pretty suddenly to ME! Actually, it's the length of time the 200 Gs are applied that counts, or "the envelope". Your thumb probably experiences lots of Gs when you hit it with a hammer, but not for long. If the gate post had moved back a foot, or sheared off and stretched the non-existant cables, there would have lots less Gs. Things have to give a little (like the SAFER barrier or the crush structure on the tranny) to lessen the impact. "Orthogonal"- ranks right up there with "quadrature" and "gaussian" in my favorite engineering buzz-word list. -Just kidding! |

200 g was the maximum through the whole accident. I think it was caused by the tub spinning like it did as it rebounded onto the track. I would be surprised if that amount of g was caused when he hit the fence.

Greg's fatal crash was 154 G, so it goes to show. Only Greg was unluckier.
Maybe after all we should look at the bigger picture... Are these speeds safe for Texas? Can they tone it down to 200-210 with less wing or engine reductions? Texas is not the widest oval there is, either. The racing at Fontana in CART is significantly safer (in terms of wheel-to-wheel closeness) since the speeds are a bit reduced. |

Crossing the road is dangerous. Crossing a six lane highway without looking is more dangerous. Oval accidents tend to have more serious consequences because of the proximity of walls and the effects of cars launching into the air at speeds of 200+ mph.
Chris Amon of Can Am and F1 Ferrari fame tried a mclaren Indy car back in 1970 and simply couldn't run competitively at speed. Proximity to the wall unnerved him. He climbed out after those two days testing and ever went back to it. Drivers make choices. Officials and organisers make choices.Regulations and design rules should be made with the object of reducing the risk as much as possible without defeating the purpose of racing. IRL cars are strong. Dixons comment after Motegi was something like "Its not a matter of if you have an accident but in these cars when..(you have an accident)" Gil won Indy, banged himself up, decided enough was enough (especially as Roger had signed a third driver) and won pole and his last race. Happy healthy retirement Gil. But the truth is he is in just as much danger riding to the local 7-Eleven as he is running at 200+ at Texas. in fact if an accident does happen he is probably more likely to seriously hurt in the road accident as he is on the race trackin spite of the lower speeds. |

The point which indicates something has to be done is that there have now been three accidents this year in which spectators would almost certainly been killed had they been in the relavent grandstand. Sooner or later it will happen if something isnt done. Reading the reports of Tony Rennas tragic accident yesterday, the gearbox and much of the car ended up in the grandstand. If that had been fullthen we are talking of an accident on the scale of Lemans 1955, god forbid. The Racing authorities need to act on the warning signs before such a tragedy happens. Forget for a second about driver safety, it is the spectators who are now at a significant risk.

But does debris ending up in stands mean that something needs to be done to the cars, or something needs to be done to the fencing surrounding the circuit.
The Brack accident wasn't a fault of the car, and if the report i read about Renna's car getting airborne after changing surfaces (from grass to tarmac), then that is hardly the cars fault. |

But why the spate of such accidents this year? Is their a tendancy for the cars to get airboure? If a car becomes airbourne at 200+mph then there is a very real danger of debris ending up in the stands and short of a 20ft high concrete wall what type of fencing is going to stop that. Also it is one thing for small debris ending up in the stands, but a gearbox hitting a stand full of people at 200mph doesnt bear thinking about.

What spate of airborne accidents? I count 4, Andretti, Wheldon, Brack and Renna.
Andretti's was caused by debris on the track, which at that speed, clipping something and getting the front wheels off the ground a few millimetres was always going to produce that result. Wheldon lost a right rear wheel which always pushes the front left up into the air, only this time he was still travelling fast enough that the air just caught it and flipped it over. The there was Brack's accident which involved interlocking wheels. All of those involved factors outside the car, and are hazzards of high speed oval track racing, the risks are always going to be higher. I'm not sure that we'll ever know the real reason for Renna's crash, but reports i've heard about him clipping the grass, to also possibly have been hitting some debris, could put the accident in the same category as the other three. Investigations will be done and probably changes made, lets just hope they are the right one's, which for me, doesn't have much to do with the cars themselves. |

I would call 4 (5 according to the article below)airbourne crashes in one year in one series a spate. I am not necessarily blaming the cars as I am not qualified to understand. But I am saying the authorities need to take a very careful look at the cars, circuits and circumstances behind the crashes as there appears to be a very real chance of a terrible crash involving spectators.
Interestingly grand prix.com have since published the attached article in which they describe the 'spate' of crashes in IRL and discuss the implications for racing as a whole. They also note that IRL cars have flat bottoms which accentuate the problems once air gets under the car. This is the same problem which has caused similar problems in sportscars including Peter Dumbrecks infamous flying Mercedes and has led to fundamental rule changes being implimented next year http://www.grandprix.com/ns/ns12081.html Last edited by Mal; 23 Oct 2003 at 14:22. |

A flat bottom was a big contributing factor to Michele Alboreto's fatal crash at Lausitzring as well. That, and the fact that the roll-hoop on the Audi didn't stand a chance when the car landed upsidedown.

In that article he says the show would be just as good if they were 40mph slower at Indy. That's around 190mph. Wouldn't that be an IPS race?

No. Speed in itself is not what makes it difficult or entertaining. Lower the grip and the HP at the same time, in similar amounts. (although IRL needs to lower the grip more than the HP)

So slowing the cars down isn't nessecarily the solution.

I'm sorry but this reply is exactly what Miller was talking about when he indicated you can't sit on your hands and do nothing. I'm not a Miller fan but his predictions about the implications of a major multiple tragedy are 100% accurate for all forms of paved oval racing. It won't just affect Indy, it will affect NASCAR, USAC etc. If you sit and do nothing, taking no responsibility for the prevention of such accidents the effects will be all the more devasting for oval racing. Pull your head out of the sand and get real.

Tony's death is a terrible tragedy, a loss for many.
I hate to sound crass, but we as auto racing fans got lucky this time. We got lucky that this happened during a test session. Had this type of incident happened on race day, our sport would be in danger of major changes. Apparently the car would have hit where the handicapped viewing section was. There is some disagreement to how much debris landed in the stands. Whether it be gearbox and major parts, or the minor parts, it still had the potentail for at minimum injury. I agree that racing drivers understand that they are taking a risk, and while unfortunate when they are taken from us, it is part of their profession. Of course, all reasonable means should be looked at in order to protect the safety of drivers where possible. I certainly hope that people are looking into safety on an ongoing basis in all types of racing, and particularly when it appears as though there may be some issues. I don't believe it is an acceptable that fans be put at such a risk. Three cars have been launched this year, and luckily there haven't been fan injuries. Something does need to be looked at to prevent cars from going into the stands, to preserve Oval Racing as an American heritage, and to preserve Auto Racing on a whole. Jackie Stewart was a great champion of safety for F1, in an era with a terrible safety record. Hopefully someone, or some group comes forth now, so that we aren't having such discussions again, or less often about injuries. |
