I remember watching a NASCAR race...a couple years ago. I thought the driver was dead for sure...his car flipped over and over and landed upside down. I believe he walked away from it, to my shock. I can't remember his name, but it was unbelievable he lived (which reminds me of your brother's miracle). Of course, their cars are ultra-ultra-protected.
Anyone remember watching the tire come off the guys rim, follow the car for a bit, and then pop back onto the rim?
I've looked for video of it, but haven't been able to findit.
(It was probably a Brickyard 500 race.)
I wouldn't have believed it if I hadn't seen it, and the announcers were shocked as well.
