I wouldn't necessarily say that I "crashed", but I was the victim of an accident. Result, a broken back (T12 vertebrae was compressed and pulverized) and possible fractured ribs.
I was riding south on US1 through Titusville, while somewhere behind me around the bend, a 16 year old kid with a learner's permit was street racing with the family car. One moment I was in the left lane passing a white SUV, and the next moment, I was airborn. I landed on my back, but I was still moving. I had landed on the hood of his car. Witnesses on the street said he was FLYING and didn't touch his brakes until AFTER he hit me.
Anyway, I'm on his hood, which confused me. I didn't realize I was on his hood... I felt like I had landed on the ground, yet I was still moving. NOW, he hits his brakes. And now I realize where I was, as I quickly slid off the hood of his car and I now worried about being run over. I hit the asphault, slid a little, rolled, and then came to a stop spread eagle on my back. Luckily, he did not run me over.
He did however come over to me, look down and said, "are you okay?" He then attempted to pull off my helmet while the chin strap was still attached. Thankfully, a person I the street told him to not touch me.
Paramedics arrived quickly, evaluated me, noticed I was guarding my left side, and the fact I had almost no feeling in my legs and feet, decided that they were probably dealing with a back injury, they pumped me full of morphine and airlifted me to Orlando Regional Medical Center. The next day, I had a back fusion surgery done, and five days after the accident I was going home in a back-brace and walker, just a few days before my birthday!
Thankfully, my helmet saved my head, my jacket saved my skin, and my boots saved my toes. I had on normal Levis and no gloves, so I was very lucky that I had hardly any abrassions. If fact, looking at me you could hardly tell I had been injured.
I was out of work for six months, and then another six months of light duty before I had recovered. Before that, I had never broken a bone in my body.
