Max Verstappen may have posted the quickest time for the first practice session earlier today, however the big story is that there was only 20 minutes of running.
That was because of an issue with the medical helicopter, which could not land at the nearest specified hospital in Shanghai due to the visibility. A nearby local airport had to also shut down due to the low clouds, and were giving updates every 10 minutes to race control on the issue in a bid to resolve and get some running.
But once the start of the second practice session was announced as being delayed, it seemed time just elapsed as no further updates on running were issued.
In the limited running they had Williams managed to get out on track in wet conditions for the first time, having missed the wet running during pre-season testing. Felipe Massa and Lance Stroll were second and third respectively, equalising the same number of laps as Daniel Ricciardo who was eight quickest.
Nico Hulkenberg caused a Virtual Safety Car after spinning his Renault into the gravel at Turn 3, which eventually led to the red flag that lasted until the end of the session.
Teams will have the opportunity to run again tomorrow morning before qualifying, however there are some doubts as to whether the race will be run on Sunday considering there are similar weather forecasts.
