A video has emerged of just how badly a Formula 1 car is affected by unusual aero conditions, after Lance Stroll believed something was wrong with his car as a helicopter flew overhead.
Formula 1's Medical Helicopter, which was evacuating Max Verstappen from Silverstone to hospital for precautionary checks after his scary high speed accident with Lewis Hamilton, flew over the Wellington Straight as Stroll powered his Aston Martin directly underneath.
The video shows the car visibly disturbed by the unusual air direction, with Stroll having to fight the car to stay in control. The Canadian was able to continue, and immediately radioed in to ask his engineer to check the car as he believed something was wrong.
With race engineer Bradley Joyce replying that all appeared OK, Stroll seemed to realise what had happened and suggested that the helicopter had had a big effect on his car's handling.
With the video being shared on social media, the intial guess was that the helicopter was an over-enthusiastic camera operator, but the FIA's Medical Car driver Alan van der Merwe confirmed on Twitter afterwards that it was the Medical Helicopter taking off with Verstappen onboard.
