I had somthing similiar happen to a friend of mine. This was about a year and a half ago. He had a Dodge SRT-4, and he had only had it for about 2 weeks(they had'nt even signed the paperwork on it yet.) Anyway, one night he was going down a straight road and was going about 130 miles an hour, and hit a bump in the road, which caused him to go airborne for about 10 or 12 feet. Thankfully for my friend, there was not a tree in the way of his landing, only a ditch. Somehow he ended up surviving the accident, but had a big cut on the back of his neck that required ALOT of stitches. He still bears the scar from it. My friend, who used to be a reckless driver before the crash, is a lot more careful nowadays of course.
