During a DTM practice session in Zandvoort, Holland last weekend there was an accident in the pit lane that left four men injured. Ralf Schumacher had finished pitting his Mercedes-Benz racer and the pit crew in front of his had wheeled out and untied their air line, and a man in the adjacent crew was holding the air line on his shoulder.
As Schumacher left his pits, his rear wing caught the air line in the adjacent pit, where it looped down from its elevated rod. Between the hose itself and the whipping metal jack at the end of it, it sent four men to the ground and then to the hospital. All of the injuries were minor, thankfully. Three of the men have been released, one is still under observation. You can watch the incident in the video below.
