Re: Question for Jeff Foster and Dave Kommel
That would be incorrect. The flash is only firing once during each exposure.

Re: Question for Jeff Foster and Dave Kommel
Never say never.....but...
I have been around drag racing for going on 50 years and I can never recall seeing NHRA rerun a final round for any reason at a national event It also seems amazing that the powers that be could decide in such a short amount of time to rerun this round as they did..... I could easily recount starting line redlight issues going back many years ago.....NO reruns were granted....period...

Re: Question for Jeff Foster and Dave Kommel
I just found out there is a video of this and being the video guy that I am I checked it out and here's what I found:
Here's the frame right before the red light comes on: Here's the next frame when the red light starts to come on: Here's the next frame when the red light comes on fully: And here's the next frame after the one above: It's hard to tell by just looking at the photos, but in the last frame you can see the reflection of the flash off of the left front corner of the car. You need to download each picture and scroll through them and it's easy to see. I just use Windows Picture and Fax Viewer and use the right arrow to go to the next picture. If I were a betting man, which I am, I would bet the camera that took the picture has the capability to trigger external flashes. And to trigger the external flashes the camera uses infrared. I don't know how external flashes work, but it makes sense that you would have to send out a signal from the camera to the external flashes before the actual flash happens so the flashes are in sync. The video has a frame rate of 30 frames per second. Which means each frame is .033 seconds apart. So I believe my hypothesis was correct in my post yesterday.

Re: Question for Jeff Foster and Dave Kommel
Look at the O'Reilly sign at the right hand top corner on the sign. Then looking at the passenger side of the car about where the parking light is. According to this the car hasn't moved in any of the four pictures...Just an observation....

Re: Question for Jeff Foster and Dave Kommel
Toby, if i'm ever involved in a close race (which is not likely) i'm going to hire you for your (DSI) Drag Scene Investigation, very through. Good job counselor.

Re: Question for Jeff Foster and Dave Kommel
If you step through frame by frame on the Mason incident video
you can clearly see the camera flashes, and they do not coincide with the red light coming on. The red light comes on *after* the camera flashes, and the the pre-stage and stage bulbs go out AFTER the red light comes on.
In the Brand incident there does not appear to be any camera flashes involved, and you're dealing with a footbrake car that staged solidly and then came up against the converter, so you are definitely not dealing with an issue of rocking back out of the beams. Once again, the red light comes on BEFORE the pre-stage and stage lights go out. This issue has also occured at a track in the east in bracket racing, and we've seen similar things happen in the Pro categories.
