Another unusual occurrence: glass on track.
Red Bull were about to send Max Verstappen out but had already delayed when a number of team members ran to the pit wall to look up and down the straight, because warning flags were being displayed.
A pane of glass was the culprit, that had fallen from the starter’s box above the track. A brief red flag saw it quickly cleared up, although it was maybe slightly too quick as Fernando Alonso headed out and then the red flag returned immediately, so he had to come back into the pits again.
Andrea Kimi Antonelli was behind Charles Leclerc, out on the track. He overtakes the Monegasque and gets on with his lap.
Lando Norris, Jack Doohan, Max Verstappen and Olvier Bearman are all in the garages.
The other drivers are out on track, getting in the laps with 10 minutes to go.
