The last driver to be killed during a race, Ayrton Senna's death at the San Marino Grand Prix on 1 May 1994 made front pages around the world, and ushered in a new era of heightened safety for F1.

While Senna has been cast as one of the sport's enduring icons in the years since his untimely death, Alan Henry's retrospective from 2 May 1994 is a reminder of the complexities of the Brazilian's character: private and introverted off the track; ruthless and singled-minded to the point of recklessness on it.

The death of Senna, and of fellow driver Roland Ratzenberger during qualification the same weekend, caused a storm of debate over safety.

Perhaps mindful of panic, Peter Cole penned this comment piece on 3 May 1994 reminding readers that Formula One had become "incredibly safe" in comparison to its earlier days, a point seemingly mirrored by the lack of a fatality for 12 years previously.

Despite Cole's ruminations, severe criticism of the FIA led to a major inquiry. Richard Williams' book extract, published in the Guardian on 15 December 1997, provides perhaps the best overview of the "lengthy and bewildering" investigation process. A day later, six members of the Williams team, including founder Frank Williams and Adrian Newey, were found not guilty of manslaughter.

The legend of Senna has only grown over time, helped by Asif Kapadia's BAFTA-winning 2010 documentary.

In June 2001 Tony Wilson, Manchester music impresario, gave an interview describing the thrill of watching the Brazilian win in style at Donington in 1993.
