Heavy fog in Shanghai prevented track running in the second Formula 1 pr♍actice session for this weekend's Chinese Grand Prix as the medical helicopter was unable to land at the local hospital.

Poor weather conditions in Shanghai through FP1 led to the majority of the session being red flagged, although a few drivers were able to get ou𒁃t and complete some laps, with Max Verstappen posting the fastest time.

While conditions over the Shanghai Internat🅘ional Circuit had improved ahead of second practice, the medical helicopter was still unable to𝔉 land at the hospital, leading to the session being suspended minutes before it was due to start.

"At the moment it can't land at the hospital which is about 38 km away unfortunately," F1 race director Charlie Whiting explained during the session. "It looks reasonable here, I know, and there are helicopters flying here, but they can't actually land at the airport💟 which is downtown Shanghai.

"We're getting news from the airport which🌳 is also affected by the low cloud, we're getting news every 10 minutes. We're just keeping up with that."

A long wait followed as the minutes ticked down, but despite circuit officials being in regular co🐟ntact with the hospital in downtown Shanghai, conditions did not improve enough to allow any runni⛄ng to take place.
