Account #1 - It happened in May, 1992. I was driving a '68 Spitfire convertible and a friend was riding as a passenger. We were driving on a narrow country road and as we entered a 90 degree turn one of the back tires separated from the rim (i.e. blew out). The car spun around and slid off the road backwards while still spinning. A 3-4 foot drop off at the edge of the road gave the car enough momentum to flip endwise.
