(Rolf Stommelen’s) Embassy Hill GH1 – #Ford-Cosworth DFV 3.0 V8 Right from the start, the drivers who were members of the Grand Prix Drivers Association were furious that the barriers were not bolted together properly. Thus, they went on strike.
Most of the sport’s major players refused to take part in practice. Jacky Ickx was not a member of the GPDA, and one of the few marquee drivers who did practice. Track staff worked overnight to fix the barriers, and to make sure everything would be fixed in time for qualifying on Saturday, some of the teams sent out mechanics to help. On lap four, the engine in Jody Scheckter’s #Tyrrell blew, and the oil dumping onto the circuit caused Alan Jones and Mark Donohue to crash. Three laps later, Hunt also slipped in the oil and crashed. The top three had become Andretti, Watson, and Stommelen. Watson’s car suffered from vibrations and dropped out. Andretti’s rear suspension lasted only seven more laps before it failed, causing him to crash out of the lead. Jean-Pierre Jarier and Brambilla stopped to change tyres, whilst Tom Pryce and Tony Brise tangled. Stommelen was now in the top spot, followed by Pace, Ronnie Peterson, Jochen Mass, and Ickx. On lap 24, Peterson was out after he tangled with François Migault while trying to lap the Frenchman. Two laps later, tragedy struck. The rear wing on Stommelen’s Embassy Hill broke, sending him into the barrier, ironically at the point that his own mechanics had worked on. He bounced off it and back into the road, hitting the barrier across the way, and flying over it. While trying to avoid Stommelen as he crossed the track, Pace crashed. Five spectators were killed by Stommelen’s flying car with the driver suffering a broken leg, a broken wrist and two cracked ribs.
