i'm trying to see exactly what went wrong, looks like it was too steep of a landing and the nose dug in? maybe landed at an angle too.
This is from the RDC post from Josh daniels, explains all what happened.
This is where it gets interesting. We are jamming down the graded road at about 115mph. No big deal, the road is really smooth and straight with only a few slight rollers. I see a big roller coming up and think I will brake into it, using not only the cars brakes, but also the roller to slow us up making it quicker on time and easier on the car.
Just as we approach the spot where I decided to brake, I see it!!! The huge drop in the road with a sharp rut at the bottom. Allen doesn't call it out because it's not marked on our GPS. There are no down arrows by BITD exposing the danger. Nothing...just a huge friggin' hole!!!! The sun is in a position to where there are no shadows exposing the danger either. I have only ran down this road once and do not remember the danger. Other guys that I have talked to know about it and are very cautious to go through it without problems. I have heard that there have been a few guys that have eaten it in this spot. Well....add one more to the list!!!
We go into the hole at 115 mph and nose the front end into the other side!!!! This sends the car sideways. I try to recover the car but the road isnt wide enough. Another 20 feet or so and I may have pulled it off. We hit the burm and go flying into the air. We go end over end for 460 ft from the spot of the initial contact!!!! From what we can come up with, the car does about 6 complete flips or so!! It comes to rest on its side never once hitting the roof, only touching the front and rear of the car.
We come to rest and i yell to Allen if he is OK!! I yell it several times and I get no response. I get a huge sinking feeling...he is either knocked out or......I don't even want to think the other thing!!! I imediatly hit the emergensy reponse on our iritrack and then radio to our crew.
