was killed during a practice session for the 1975 Austrian Grand Prix. On his second lap, while at about 260 km/h a rear tire of his March 751 – Ford suddenly blew, the out of control car went through the fence for about 180 feet, over a guard-rail and into a ravine. Donohue was hit in the head by a fence post and knocked unconscious. Several minutes later Donohue regained consciousness. There is film of him speaking to his rescuers and looking quite un-injured. He was taken to the hospital for observation. During the day he became confused and slipped into a coma, classic signs of a sub-dural hematoma that every nurse and doctor knows today. He was operated on later that night by a neurosurgeon but he died of his injuries two days later. This type of death is extremely unlikely today with much more knowledge of closed head injuries and better training of track medical staff that can recognize the early signs of brain injuries and blood clots. The universal use of CAT scans for any racing driver who is even suspected of having a closed head injury is another reason why racecar driver’s deaths from this cause are rare and should probably never happen. If you complain of a headache or a loss of consciousness after a crash, my fellow racers, you can expect a trip to the local hospital for a CAT scan of your brain. You can thank Mr Donohue for helping save many future racers.
