I searched, but did not see anything.
But there was a fatality at HyperFest on the Jefferson circuit. During HyperFest on Sat, they run a sort of DE like event called HyperDrives. The participants sign up for single track sessions with an instructor (no solos).
Last session, the car hit a tree, sideways, and crushed the instructor.
Some reports state the driver exited the turn, hit the throttle and the rear end came out. The driver stayed in the throttle and the car exited the paved surface. Supposedly the student had done multiple sessions.
It was stated a left turn, without runoff area. I am thinking it was exiting the downhill left hander onto the straight (counter clockwise direction).
