A good Friend of mine blew his chevy powered front-engine dragster at norwalk and a piece of it hit a guy in the forehead while sitting in the stands. Not a bad cut but a bleeder and when the guy sitting in front of him turned around he passed out. Shortly after that track personnel came walking around having us sign a track insurance rider. When that thing blew the separated case spun around and luckily an ear caught a moly frame tube (and bent it) as it was going to keep spinning between his legs. The transmission blanket looked like ground up fiberglass and it shredded his Morse cables. I heard that years later a lawsuit was filed.
