AMuS published last month in their magazine a story about the accident database of the FIA which was founded in 1996. Yesterday they also published it on their website. I think it is quite interesting and I would like to share it also with non-German-speakers.

They got the data from 11 crashes in the past (2 in the WEC, 9 in F1). As an example they also got the detailed analyses of Webbers crash last year in Sao Paulo

Unfall-Mark-Webber-WEC-Interlagos-2014-F
On the first datasheet they have all the data about the speed of the car, on which speed the driver lost the control of the car, with which speed he suffered the impact, how much time past between the control lost and the impact, which angle he had at the impact, etc. Furthermore on this sheet they also listed the Accelerations.
Unfall-Mark-Webber-WEC-Interlagos-2014-F
On this datasheet you can see on which direction of the car we had the Accelearation (red) and the loss of velocy (black).
Unfall-Mark-Webber-WEC-Interlagos-2014-F
This datasheet is a bit more detailed: On the left we have the acceleration in the moments of the impact (within 300 ms). On the right the velocy change in the moments of the impact. The graph below is shows how much the car got deflected after the impact.


AMuS also did an interview with FIA-accident-reasearcher Andy Mellor (google translate)

Lol. As soon as he got in the car had lost control.

That's incredible detail. It'll take a while to work through all that.

The speed and impact from Simonsen is hard to believe that this would be fatal!!!

 

Especialy compared to Webbers crash!

Driver's side into a barrier that was directly in front of a large immovable object (a tree). Not really that hard to believe. Plus the GT cars have completely different crash structures to Prototypes.

Yeah that part I do understand. But just over 70 kilometers pro hour (not miles) in a manufactured racecar with rolbar and all other protection isn't usualy fatal. As for the crash of Webber, Davidson and if I recall correct McNish such crashes usualy are more dramatic by outcome.

It really puts David Purley's accident in 1977 into perspective. 173 kph → 0 in 66 centimetres, and deceleration of 179.8 G. How could he ever survive THAT one...

That was quite a frightening accident at the time as IIRC Sato stayed in the car and wasn't seen to move for quite a few minutes with the medical team sorting him out still strapped in his seat.  I can't remember if he missed a race or two after.  For those minutes I thought we were looking at a fatality.

Just in case you didn't know he was hit as he accelerated out of turn 2 by Heidfeld who failed to brake for the corner and simply ran across the apex at speed.  He didn't lose control.

Heidfeld did brake and it spun the car, it's what made the crash so bad as he went into Sato gearbox first.

The bianchi was almost completely forwards into the recovery truck and had a peak g force of 290g ish. This is not what is stated in the OP.

 

Also button 2003 vs perez 2011 were very similar but button's crash was slower. JB was knocked out but perez only had a concussion. That is a good improvement of crash safety in less than 10 years.

Bianchi was different. They explain it in their article. The pure crash with the car was just 58.8g - easily survivable. Problem was that he hit with the helmet the crane and by calculation he reached 290g just on the helmet.

He was moving forwards when he got t-boned.

I remember that Sato was moving in the car but couldn't get out. My initial thought was that he would have a broken leg or some other foot injury.
