It's like that Le Mans Mercedes crash, just a lot heavier.
When you start getting into the world of purpose-built drag cars, cars made without concern for the laws which govern street cars, you can get into some pretty insane horsepower and speed figures. So a 3,000 horsepower Mustang is the sort of thing you can expect to see at a drag strip. But the kinds of speeds a car like that is capable of aren't what Ford originally had in mind for the shape of the body, and sometimes things go a bit wrong.
The driver, one Dennis Bailey, walked away shaken but unharmed. At least the safety equipment was up to scratch.
