Harvey Postlethwaite
In the run-up to the race, Tyrrell had lost talented designer Harvey Postlethwaite to the Mercedes-Benz sportscar team. Meanwhile, Ayrton Senna had been injured in a jet-ski incident, but he also suffered a big accident at the high speed Peraltada corner during qualifying, in which the car rolled and landed upside down, but thankfully he emerged unscathed.
