Senna left McLaren at the end of 1993 to join Williams and was killed in only his third race for the team when the 34-year-old Brazilian crashed on the seventh lap of the San Marino Grand Prix.
Over the years Senna drove for McLaren from 1988-92, the moments of fun Dennis shared with a man who was not exactly famous for his mischievous side have a special place in his heart. Driven and focused at races, Senna was indeed game for a laugh with people he knew intimately.
