SHANGHAI, China -- The second practice session for the Chinese Grand Prix was abandoned after poor weather conditions in Shanghai prevented the medical helicopter from being able to land at its designated hospital.
Although conditions at the circuit were fine for the session to take place on track, smog and low cloud at the hospital in the city meant the medical helicopter would not have been able to land if it been called into action. Under the FIA's sporting code a driver evacuation from the track "must not, in normal conditions, exceed approximately 20 minutes", meaning the session could not take place on safety grounds.
