The session was stopped whilst doctors attended to Ratzenberger. The session was started approximately 25 minutes later, but several teams—including Williams and Benetton—took no further part. Later in hospital it was announced that Ratzenberger had died as a result of his injuries. His death marked the first Formula One race weekend death since the 1982 Canadian Grand Prix when Riccardo Paletti was killed. It had been eight years since Elio de Angelis died testing a Brabham car at the Circuit Paul Ricard. Professor Sid Watkins, then head of the Formula One on-track medical team, recalled in his book about himself, Ayrton Senna's reaction to the news, stating that "Ayrton broke down and cried on my shoulder." Watkins tried to stop Senna from racing on the next day, asking "What else do you need to do? You have been world champion three times, you are obviously the quickest driver. Give it up and let's go fishing," but Ayrton said that, "Sid, there are certain things over which we have no control. I cannot quit, I have to go on."
