I've have made an interesting observation, but I'm not quite sure, if it is know already.
Here you can see a picture of Ayrton Senna at Imola 1994 just before his accident:
Something at the suspension is wrong (marked with red circle). For comparison, here a picture from the start. There you can't see it.
You can also see it on the onboard footage of the last lap (http://www.youtube.com/watch?v=RByKFxeb ... ture=feedf).
At second 5, everything is ok.
But then, at second 39 you can see the same thing at the suspension as on the pic above.
In the onboard footage you can see that it appears the first time in the corner at second 20.
So my question: Is is an interesting observation?
