Nigel Mansell's return to Williams in the middle of 1994 as a 'guest driver' was as remarkable as it was unexpected, given the circumstances that surrounded his departure at the end of his '92 world championship-winning season.
As ever, drama and excitement accompanied Mansell's comeback, and that is of course why Bernie Ecclestone engineered the second coming of one of the F1s biggest box office draws in the first place. And like much else that happened in '94, it was a direct result of the San Marino Grand Prix at Imola.
Mansell was enduring a difficult second Indycar season with Newman/Haas and was about to head into the 'Month of May' at Indianapolis when his long-time rival Ayrton Senna was killed.
