Just a preview of the above link: We lost a probe during the drive, mid-curve/turn. It was a roll-over accident caused by possible mechanical failure. The driver is, thankfully, in great shape with only a large bruise on his shoulder from the seatbelt holding him in.
Sorry to hear about the near tragedy at the meet.. I'm glad no one was injured.
I don't know if "fast cornering" preceded the tire loosing air and wheel folding under, BUT: When going onto a tack or road to do enthusiastic corning it is important to inflate all tires to near maximum in order to keep the tire from coming off the rim in hard corners.. just something you should all keep in mind..
