About 10 years ago Cruz had a boomer at Pomona. A chunk of windshield hit the seat next to us in the stands at 1,100 feet.
I was sitting where I always sit at around 100', and it looked exactly like Tony's Boomer! He's lucky that chassis didn't snap, whoever built that car knew what they were doing!

I am not an expert on this, but I think the head travelling forward of the roll cage is inevatable given the rapid decelleration. Check this photo of the Greeks head during decelleration due to the blower belt coming off.
I would Imagine the deceleration in Urs case was much more dramatic and Urs is a much taller guy than the Greek, thus the further head movement.

It appeared chunks of tire and engine shrapnel landed in RV area off to the right of the track. Dang, that was a big bang and the heat/smell from the fire was quite palpable from where Greg and I were sitting. That was certainly a huge relief to see Urs keep that car as straight as possible. I would imagine it took some serious strength to manhandle it the way he did.

So you and Greg were all by yourselve's, Mark? LOL 
Seriously....we all felt the heat and concussion from where we were sitting and we were pretty high up in the stands, but it pretty much happened right in front of us. The first thing Paul turned and asked me was...Did you feel that heat? That was one major fireball! It made me a little nervous that he took so long to get out of the car!

I was also sitting in the section at the end and felt the heat and concussion from the boomer. That was definitely a mechanical failure of some kind! It reminded me of the explosion Mark Kinsella had in E-town. I was doing the clutch for him and we had the block split in the first round against Cory Mac. All hell broke loose and pieces went everywhere.
On another note, it was nice to meet you Kelly, Greg and Mark.

I heard it was a broken timing gear on the crank...

Urs said it was a broken valve. The article is on Comp Plus I think.

When the gear drive breaks, it then crashes many valves. That makes the fire ball much larger that a single intake.
I've dropped the head off a single intake valve ,and it only opened the burst panel ,the blower stayed on the manifold. Now granted that was in the 45 gallon days.
Urs deal also destroyed the manifold, 90 gallon fuel pumps don't forgive.
