On this day nineteen years ago, May 1st, 1994, we lost arguably one of the greatest drivers to ever live, Brazilian Ayrton Senna. Senna, who was driving for Williams, was leading the 1994 San Marino Grand Prix before losing control in Tamburello Corner and hitting a concrete barrier. Telemetry shows that Senna was reaching speeds of approximately 190mph on that straight but got the car slowed down to about 135mph before making impact. Unfortunately, his helmet was penetrated by a piece of suspension penetrated his helmet causing trauma Senna was later pronounced dead. The cause of the accident remained a mystery for the longest time, but it was determined that the steering column had broke in the car causing him to have no control. The day before Ayrton's death, fellow driver Roland Ratzenburger died in a crash during qualifying. It marks one of the darkest weekends in motorsports history. Rest in peace Ayrton and Roland.
