(Mark Donohue’s) #March 751 – #Ford-Cosworth DFV 3.0 V8During a practice session for the race, Donohue lost control of his #March after a tire failed, sending him careening into the catch fencing at the fastest corner on the track, Voëst-Hugel. A track marshal was killed by debris from the accident, but Donohue did not appear to be injured significantly.
It is said that Donohue’s head struck either a catch fencing post or the bottom of the wood frame for an advertising billboard located alongside of the racetrack. A headache resulted, however, and worsened. After going to the hospital of Graz the next day, Donohue lapsed into a coma from a cerebral hemorrhage and died.
