This was Toro Rosso's Sebastien Buemi just a few laps into the first practice session in Shanghai.
I can't recall ever seeing anything like this. Maybe Kimi Raikkonen's suspension failure with Mclaren, but that was just one side and after running many laps with a square wheel. This was just incredible, Buemi is very lucky.
Another thing to add is...what happened to the wheel tethers? the right wheel looks like it end up nailing one of the the cameras.
Toto Rosso says it's the upright that failed. From the video it looks like it was the carbon fiber arms that failed and the failure of two "aluminum" upright/hubs at the same time seems impossible. Readers need to help me out here, I remember F1 teams were running or at least experimenting with a front axle system that distributed braking torque between the wheels. Might that explain why both sides failed simultaneously?
