The first free practice session in China has been suspended for a minimum of thirty minutes, due to the medical helicopter being unable to land in the designated hospital in Shanghai.
Clouds of mist and fog greeted the drivers as they made their ways to the track, and thickened as the session got underway. With safety being the number priority, Charlie Whiting took no risk and deployed the red flag.
