Toro Rossos narrowly avoiding huge collision, Vandoorne out in Q1
If 38-year-old Kimi Raikkonen gets pole then he will be the oldest polesitter since 41-year-old Nigel Mansell grabbed top spot during his brief comeback with Williams in 1994.
At the other end of the age range, 20-year-old Max Verstappen has never had a pole position and will become the youngest driver in Formula 1 history to do so if he does today.

Earlier today, Great Britain's Lando Norris retained his lead at the top of the FIA Formula 2 Championship by coming sixth in the hour-long feature race in the second weekend of the competition.
Norris, 18, part of McLaren's Young Driver Programme, qualified in second place but stalled on the formation lap before recovering to take sixth after winning the feature race in Bahrain earlier this month.
The race was won by Thailand's Alexander Albon, while another Brit, Jack Aitken came second with George Russell 12th and out of the points.
But all the drivers have more opportunities for points tomorrow with the 45-minute sprint race (10:10 BST), where Norris will start third on the grid.

Williams say they expect to be able to get Sergey Sirotkin out for qualifying after his crash in final practice.
But there will be a five-place grid penalty for Renault's Nico Hulkenberg for a gearbox change.
Image source, Getty ImagesThis is probably how Nico Hulkenberg is feeling now..
Lewis Hamilton was in dominant form last year in qualifying in Azerbaijan.
Click on the link below (courtesy of the official Formula 1 Twitter account) to see how he got himself on to pole position with a two-second advantage.

Welcome back. We have had numerous drivers struggle in Azerbaijan, some have gone into the wall and many have slipped off the track, but who can sort it out when it matters?
Let's find out with qualifying.
It is all set up nicely for qualifying. We are taking a short break and will be back at 13:00 BST.
And these were the times from the third session, as you can see it was the purple ultrasofts everywhere, apart from Nico Hulkenberg and Carlos Sainz who dabbled with the red supersofts.

Image source, Rex FeaturesFerrari's Sebastian Vettel set an imposing pace as he headed Lewis Hamilton's Mercedes in final practice at the Azerbaijan Grand Prix.
The German was 0.361 seconds clear of Hamilton, who trails him by nine points in the championship after three races.
Ferrari's Kimi Raikkonen was third ahead of Red Bull's Max Verstappen.
The Dutchman leapt to fourth in a last dash after a crash by Williams' Sergey Sirotkin had brought out the red flag and left time for one flying lap.
Image source, .Three sessions gone, and Lewis Hamilton has not been fastest in any of them. Sebastian Vettel takes the glory in session three, after Valtteri Bottas and Daniel Ricciardo had been quickest in sessions one and two respectively.
Image source, Getty ImagesMax Verstappen takes advantage of that bonus last lap, he moves from seventh to fourth. Daniel Ricciardo can't improve on his 12th after a mistake in the middle sector.
The drivers are heading back out there, they only have two minutes left to get one flying lap in. This could be crazy.
