Nico Rosberg was lucky to avoid a big accident during Friday practice for the Belgian Grand Prix after suffering a spectacular tyre failure.
The right rear tyre on the German's Mercedes failed on the long run down to Blanchimont corner with just less than 30 minutes of practice remaining.
The incident pitched Rosberg into a spin. But despite snaking down the track and looping around, he eventually came to a rest in the run-off area without hitting anything. The session was red-flagged.
Speaking on his return to the pits, Rosberg said: "It was definitely not fun. I don't know what happened, I think the tyre broke on the rear - let's wait and see."
Debris or failure?
The cause of the tyre failure was initially unclear, and it could be that the tyre failure was related to possible debris damage.
When asked by the BBC about if he suspected debris as a cause, he said: "There was no debris. I don't think so."
However, it is widely known that the high-speed characteristics of the Spa-Francorchamps circuit are especially challenging for tyres.
Rosberg's set of tyres had done 11 laps in total prior to the incident.
