I was there, in the same stand as the videographer & it was horrific! Upon hitting the concrete barrier the car just exploded into bits of carbon fibre! The main body section of the car then crossed the track and hit the other wall, where he finally came to a stop! Amazingly, he drove home from the hospital the following day!
it was frightening...it was a long 15 minutes or so until we heard that he was going to be ok.
i can't imagine what Scott Speed was feeling- his broken car was parked in the right foreground behind the first barrier & he was sitting maybe 20 feet behind his car when Kubica slammed into both walls! Man, was he close- he probably got hit with debris!
Amazing!
