Brian dropped #1 Intake Valve, engine caught on fire and body buckled from the explosion. The front body latch released, the back one did not. He popped his fire bottles which, in theory, is correct, however, when the body caught air, he went airborne with it and it sent him 180 degrees in the air, landing going backwards and slapping the wall hard. He was still on fire when sliding backwards, we were going on scales and I still had my suit on so I took off running to him because no other emergency personnel had time yet to get to him. I got about 10 feet from the wall an official way behind me was telling me I had to stay clear, I kindly mentioned that I was dressed better in suit with boots on than he in street clothes to help him and kept running. As I turned back around he was out and telling the car some choice words (LOL) I knew he was ok and then ran back to the scales. Glad my foot hung in there from running through the grass area.......... I'm very glad that our fellow competitor was okay, that was the most important thing.....Not sure about the other person, only have heard that he was stable....I hope he has a full recovery as well...
