Here's the result of Force India reserve driver Daniel Juncadella's crash from the first session. It also explains why Sergio Perez has had to sit out this session.
There's a hairy moment in the pit lane when Felipe Massa is released into the path of Kimi Raikkonen, who in turn has to brake to avoid hitting the Williams. The team may be penalised for an unsafe release.
The red flags are a real pain for the teams as it is disrupting their long-run data gathering. It will be particularly frustrating, especially if the expected rain hits tomorrow during final practice and then qualifying as it'll make strategy for Sunday tricky.
The track is clear so we're back under way with 17 minutes remaining.
The rest of the field return to the pits while they wait for the marshals to remove Fernando Alonso's stricken Ferrari.
Fernando Alonso has stopped out on track with huge plumes of smoke pouring from the rear of the Ferrari. Big flames then lick upwards. The Spaniard jumps out of the car, grabs a fire extinguisher and quickly attends to the flames himself. The red flag is out.
Lewis Hamilton reports that the "car feels good, I just haven't hooked up a lap yet". The Briton is currently doing a long run.
We've entered the long-run phase of the session, when teams fill the cars with fuel and send drivers out to complete a succession of laps to simulate stints in Sunday's race, They can then use that data to plan strategy.
With half an hour to go, here's how they stand:

Kimi Raikkonen goes third quickest, six tenths off the pace in the Ferrari. Next time around, he runs off track at Turn 12 after locking up. The Finn has been mowing a lot of lawn today.
If you missed first practice, when Nico Rosberg beat Lewis Hamilton to the fastest time, you can watch it here.
This morning, Max Vertsappen took a wrong turn when he ran wide and ended up exploring the escape roads behind the barriers before rejoining. Watch it here or via the highlights tab at the top of the page. It also reminded me of 2012, when a similar thing happened to Kimi Raikkonen. Only that time, Raikkonen hit a dead-end and got stuck whereas Verstappen found a way out.
Lewis Hamilton is off-track again, the Mercedes driver skating off at Turn One. There's plenty of run-off there, though, and he's soon back on his way.
Good effort from Daniil Kvyat, who goes fourth quickest in the Toro Rosso. The Russian is bumped down a place to fifth after Felipe Massa (pictured) slots into fourth in the Williams.
No he can't! Lewis Hamilton runs wide, losing a bunch of time at Turn 11. The Briton crosses the line, sixth tenths of a second off the pace set by Nico Rosberg.
Nico Rosberg goes quickest with an impressive lap of 1:12.123 on the soft tyres. Can his team-mate Lewis Hamilton, who isn't too far behind, better that?
Not only is Kimi Raikkonen without a top four start all year, but he's now driven in 81 Grands Prix since his last pole, which came at the French Grand Prix in 2008 (pictured). The Finn is currently sixth quickest.
Red Bull's Daniel Ricciardo bolts on a set of soft tyres and goes quickest with a 1:12.856, just over a tenth quicker than Lewis Hamilton, whose current best time was set on the medium tyres. The Australian then cuts the corner at Turn One as drivers continue to struggle for grip.
Jenson Button is having a better time of it this afternoon, having not set a lap time this morning. The Briton has clocked 14 laps, with a best time of 1:14.772, which is good enough for 12th.
Sergio Perez will not get any running today as his Force India team say there is too much work to be done on his car, which was damaged by Daniel Juncadella this morning, before the end of session. "There was a lot of heat soak which may have damaged some engine hydraulic components," say Force India. "These components are being changed as a precaution."
