HEADING into a curve that the Formula One genius Ayrton Senna knew very well at the San Marino Grand Prix, there was no sign it would be the Brazilian’s final moment.

But rather than his blue Williams racing car turning into the Tamburello left corner, it sped at 190mph straight into a concrete barrier.

Thirty years on from the three-time world champion’s death, serious questions still remain about how a man revered as the motorsport’s greatest talent could have lost control of his hi-tech vehicle.

Was it really a driver error? Or were ill-judged modifications to Senna’s car to blame?

Investigators in Italy believed members of the British-based Williams team were at fault.

Conspiracy theorists have asked why it took the company a month to hand over the black boxes to the authorities and why they arrived so badly damaged.
