The race restarted at the end of lap 5. Senna tried immediately to pull away from Schumacher, whilst Berger in 3rd was already 2.586 seconds behind and Hill in 4th was 5.535 seconds behind. At the start of the 7th lap, Senna lost control, for reasons that are still the subject of controversy, and his car went straight on at Tamburello into an unprotected concrete wall. Telemetry shows he left the track at 310 km/h (190 mph) and was able to slow the car down by braking to 218 km/h (135 mph) in slightly under 2 seconds before hitting the wall. The suspension of the Williams broke on impact, the right front tyre flying backwards and hitting Senna on the head. The car slid to a halt on the circuit, with Senna motionless. From the helicopter pictures, a slight movement of Senna's head gave a hint of hope. Doctor Sid Watkins was on the scene in less than two minutes. Senna was airlifted to hospital but nothing could be done and Senna was pronounced dead later that evening. After the race, a moving detail was revealed when an Austrian flag was found in the Brazilian's cockpit because it is thought Senna had planned to pay tribute to Ratzenberger after the race. The race was immediately stopped after Senna's crash.
