Yesterday's practice for the German GP was cancelled due to fog. The medical helicopter was grounded, unable to fly safely in such inclement conditions.
Fog. Nebel in German. Nurburgring, 1936, where Bernd Rosemeyer scored his most famous victory. All was well with the field until thick fog descended, and the pace slowed. Rosemeyer was the exception. He simply drove away from the rest at unabated speed, and 'cruised' to victory by a country mile.
Bernd left the circuit with a large trophy, and the new title of Nebelmeister (Fog Master). It must have been quite an occasion.
