Rain had been forecast, but what actually hit the Nürburgring partway through the race was closer to a flash flood — a sudden, torrential downpour that overwhelmed the circuit's drainage faster than teams or drivers could react. Several cars aquaplaned off at the same corner in quick succession as the water rose.
Lewis Hamilton, in just his rookie season, was among them, losing control at high speed and burying his McLaren deep into a gravel trap. The car was stuck fast, and marshals — in a moment that drew real controversy afterward — physically helped push and dig the car free so Hamilton could rejoin, raising questions about whether outside assistance should have ended his race outright rather than letting him continue.
Amid the chaos, Spyker's Markus Winkelhock — making his first and, as it turned out, only Formula 1 start — had gambled on wet tyres before the rain arrived and found himself, briefly and almost unbelievably, leading a Formula 1 grand prix in a car that had no business near the front. The race was red-flagged entirely as the flooding became undriveable, then eventually resumed once conditions improved enough to continue.
