Zandvoort 2012 DTM accident pit lane

Four trackside mechanics were injured when a racing car caught a cable under their feet and flipped them into the air.

The men were working in the pits when the high-speed vehicle driven by Ralf Schumacher powered past.

They were launched skywards when the former F1 driver's Mercedes struck a fuel cable.

The accident happened during a practice session for a touring car race in Zandvoort, Holland, this weekend.

The crew members were taken to hospital by ambulance but three were released and one was kept in for observation.
