Call me crazy,but in the case of run away cars at high speed,why doesn't NHRA cosult the US Navy about a catch wire like used on aircraft carriers to stop planes weighing over 17K pounds in about 250" at speeds over 200 knots?A lot of fine details but maybe they could be overcome.The wire could be raised by someone at the end of the track when needed as can the tail hook when the situation arises.Slower cars wouldn't be affected by the system.Just a goof ball idea by a blathering idiot who doesn't want to see anyone else severely hurt or killed doing what we enjoy.

Possible downside to a carrier style catch wire is that it will be above the track surface at least an inch or so, which could put the racer airborne. Just a thought for consideration......

Midway in Chicago is using the foam/concrete blocks at the end of the runway. They were installed after the plane overshot the runway, broke throug the fence, drove out onto a city street and killed a boy in a car on 55th Street which runs along the perimeter.
If they can stop a runaway airplane, and if the weight to crush equations could be worked out right (obviously a race car doesn't weigh as much as an airplane nor distributes it's weight the same way), this might be a viable solution. Obviously what some tracks are doing isn't working as planned. It's an unfortunate and costly game of trial and error. |

some sort of devise to elevate it up to the paved height when needed.Of course every fast car,TAD/TAFC/TFD/AAFC would need a remote activated tail hook.Sounds a bit far fetched but I wish they would come up with something. I personally think they'll take the easy way out and just mandate a slowing down of the cars.

You can't back up the track at Englishtown because you'll run into the overhead tower and the sound barrier concrete wall. You can't extend the trap more than 20ft without hitting Pension Rd.
What could be done, though I don't know how well it would work, would be to construct a 45-degree left turn with enough banking to guide a car that gets past everything else onto the field that runs parallel to Pension Rd. That would give a few hundred more feet stopping room. Englishtown top end: http://www.bing.com/maps/default.asp...shtown%2C%20NJ |

I was wondering why the chute just fell off of the one car and the roll cage was completely "broken" off the other car?

I'm pretty sure they cut the cage off of the top of Neil Parker's car. That is standard operating procedure for removing an injured person from a wrecked race car. It's actually SOP for removing injured persons from most any wrecked car. The first concern for emergency personnel is to get the injured person out without causing further injury. If you take them out the top, you can do a better job of keeping the spine aligned. If you have to turn them and lay them over, odds are if there is a spinal injury, you'll make it worse. It is interesting to note that the car that crashed last year lost its chutes, and reportedly lost its brakes, yet it went through both nets, but the second net was still holding the car somewhat, and the tire barrier stopped it. In the crash this year, the car evidently, from the photos, went through the tire barrier, and was a good distance past the tire barrier. It would appear that this year's crash was at a much higher speed.

I believe, in the Alexis Dejoria accident in 2009, when the 'chutes ripped off, they tore the brake lines too.

It probably is time, and a good idea, for NHRA to look at taking some power away from the fuel cars, as they've far exceeded the design parameters of the tracks, and some of the parts they're using. Some of the older, more experienced crew chiefs have been saying that quietly for years.
If they simply took 50 cubic inches away, limited compression, and restricted blower speed, they could take 1000HP or more easily. For the cost of new pistons, new cranks, and new blower pulleys. The result would be the ability to return to 1/4 mile racing, less expense for the teams, and less time and money wasted on oil downs and fires. The use of tailhook arrester gear on race cars probably isn't too practical. An entire new structure would be required for the back of the cars, requiring a whole new level of engineering. And it should be noted that these cars are not designed to be pulled or stretched, it might be necessary to redesign the whole frame to withstand the forces acting on them from stopping them abruptly by hooking the back of the car. Otherwise, it rips the back of the car off, and then catapults it further down track. Pulling cars apart is not a good idea. Further, even the best carrier pilots jump the wire, so there's no sure way to make sure the cars catch the wire, if the car doesn't catch the wire, the system is useless. Perhaps a better idea is to use the braking technology from arrester gear on an improved catch net. The cars are designed to protect the driver from a front end crash, so the net shouldn't require massive changes to the cars. A stronger net, designed to actually capture the car, coupled to a braking system might do the trick. It's not going to tear the cars up any worse than the current system, either. A longer sand/gravel pit, starting sooner, might be another improvement. Starting the pit earlier, and making the entrance less aggressive, might help stop the cars from skipping over it, as well as giving them more time to slow down gradually. It would also stop the slower cars less abruptly, with less damage and less chance of serious injury. It would allow an extra net or two as well. If we had two regular nets, possibly somewhat stronger, and better mounted, that would slow the cars more gradually, and stop some cars completely. Then, with a third net, with arrester gear style braking, as a final fail safe, you have a system for the fastest runaway cars.
