Happened at the Red Bull Ring in Austria. The first two (team mates, coincidentally) involved were taken to a hospital, one with injuries, the other to be checked just in case. The third, Piquet, was reportedly not injured. [ame="https://www.youtube.com/watch?v=4xIaa2vFNT0"]Red Bull Ring European F3 - Huge Crash (Piquet - Li - Tveter) - YouTube[/ame]
It never ceases to amaze me the safety advances in the sport...Not that long ago there's probably 2 deaths from that.
