In the 1994 San Marino Grand Prix, during Friday practice Rubens Barrichello was launched over a kerb and into the top of a tyre barrier at the Variante Bassa, knocking the Brazilian unconscious, though quick medical intervention saved his life. During Saturday qualifying Austrian Roland Ratzenberger crashed head-on into a wall at over 310 km/h at the Villeneuve corner after his Simtek lost the front wing, dying instantly from a basilar skull fracture. The tragedy continued the next day, when the three-time World Champion Ayrton Senna lost control of his car and crashed into the concrete wall at the Tamburello corner on Lap 7. Senna died in hospital several hours after his crash. In two unrelated incidents, several spectators and mechanics were also injured during the event.
