Jim Head speaks on Orbit ESPN about Eric's accident
Discussion
Jim Head was interviewed by Gary Gerould about Eric Medlen's accident. At first Jim was going to add at least four inches of padding to his roll cage. Then they found out that the car glancing the wall didn't cause Eric's concussion, it was ?severe vibration that transferred to the rear tyres causing Eric's head to be shaken violently which caused his concussion.
Jim is going to add a titanium shield to his roll cage (like the Top Fuelers), with approx. TEN inches of padding.
NHRA will definitely make some changes mandatory, we'll just have to see what they are and if they become mandatory in European drag racing.

Would suspension of some sort work in the driver area? Maybe a seat like trucks have with air bellows or springs as suspension etc!
j s l have no idea, l'm sure John Force's team, all the other teams & the NHRA will come up with something to ensure this doesn't happen again.
Someone has suggested that all drag cars carry a Black Box Data Recorder, similar to those carried on all commercial airliners, but a scaled down & much cheaper version.

On the Discovery Science Channel this afternoon they were demonstrating The Car Chip http://carchip.co.uk/datalogger.php The CarChip #8225EX with Alarm will automatically generate an accident log showing the last critical 20 seconds of speed.
lf they modify this l'm sure it could be used on drag cars.

What, like some kind of datalogger?
Yes, but unlike the Racepak Computer carried on current drag cars. The Car Chip http://carchip.co.uk/datalogger.php The CarChip #8225EX with Alarm will automatically generate an accident log showing the last critical 20 seconds of speed.

How will it know to start recording 20 seconds before the crash?
Perhaps if it could be hooked up to provide an audible warning 20 seconds before the impact rather than starting recording, this could be a more useful feature?

At a guess it has a 20 second buffer and continually overwrites it, stopping on impact thus leaving 20 seconds of data.
How well this would cope with the extreme forces of a Top Fuel crash and how useful it would be I can't say.
