• A scary wreck on the first lap stopped the British Grand Prix.
• Rookie F1 driver Zhou Guanyu appeared to tangle with George Russell and slid across the track upside-down.
• Russell immediately left his car and ran to check on Guanyu who was taken away in an ambulance.

A scary wreck brought the British Grand Prix to a stop on the first lap.

Rookie F1 driver Zhou Guanyu of Alfa Romeo got tangled up with George Russell of Mercedes in the first corner at Silverstone after Russell was clipped by Pierre Gasly of AlphaTauri.

Guanyu's car ended upside-down and slid across the track for a long distance before flipping over the tire barrier.

Guanyu was taken away in an ambulance. F1TV reported that he was conscious and moving and appears to have avoided any serious injury. 

A radio message to teammate Valtteri Bottas sounded optimistic about Guanyu's condition.

"Zhou is conscious," a team member told Bottas. "He is talking. There is no fractures and considering the circumstances, he is pretty good."

Guanyu's car was destroyed, but you can see that the halo around the driver's head did its job and is still intact.

Here is an aerial view.

Russell got out of his car and immediately ran over to check on Guanyu.

Here is the original call on F1TV.

The wreck brought out a red flag as the race was stopped for a lengthy delay.
