Sebastian Vettel heads in for his second stop of the race, takes on a set of hard tyres, 2.2s and he is back out in fourth.
Meanwhile, front jackmen are earning their money today! Romain Grosjean heads in, overshoots and one of his team is sent tumbling to the ground, jack in hand. Ouch.
Grosjean even collected his front left wheel man as well.

'It was scary'published at 14:04 British Summer Time 10 May 2015
Fernando Alonso, speaking to BBC Sport's Lee McKenzie: "It was scary. I had no brakes for the whole in-lap, and for the pit stop it was even less.
"I'm disappointed for the retirement but the only thing we can do now is investigate and come back stronger for Monaco.
"We are a long way off and we need to make double steps because everyone else is improving.
"This is a very challenging project, but I'm happy that we're recovering well and we need to keep it up."

Ferdi Tjombe: One step forward and two steps back for McLaren.

That moment David Coulthard mentions happened after Fernando Alonso ran wide at Turn One.
He corrected himself and got back to the pits but overshot his stop and sends a jack flying 20 metres in front of him. Luckily, no-one gets hurt, but his race is over - almost certainly because of the brake problem.
