@SRK: If the car had become live, it could have given a shock to the driver. This was a question swirling around the paddock on Sunday but it's very important to clarify it was only speculation. What's most likely is the crash structure of the McLaren failed to do its job properly, meaning the driver and not the car absorbed most of the impact with the wall - hence the concussion.
Raikkonen comes into the pit lane after a handful of laps on the medium tyre. No big stints from anyone so far.
Button heads out for our first glimpse of the McLaren since Alonso's accident.
Lots of sparks flying from the back of Hamilton's Mercedes as he roars down the pit straight. The world champion on the medium tyre. Massa following not far behind on hards.
Hamilton's first time of the day is a 1:31.669 as he slots into second.
But Massa goes 1:27.105, leaping into first. The Williams driver has the hard tyre on. Expect these times to keep tumbling in the early stages of the day.
Something I missed earlier, a brief red flag for Daniil Kvyat, who stopped his Red Bull at the end of the pit lane.
Nice shot from our friends at Sutton Images there.
Hamilton takes the top spot with a 1:26.787.
I don't believe so. He has chosen to keep #44 for the current season. Under the new rules a world champion can keep his career number even when the defending champion.
@Marais: They can come! There are a few little groups in the grandstand opposite the media centre. It doesn't help that it's a Thursday, though. The weekend was slightly busier last week.
@Russ: Generally this test gives the best idea of performance, yes. We'll likely see longer runs as the session goes on and can try and make some sort of comparison, though we still don't know fuel loads etc.
Hamilton lowers the benchmark further to a 1:26.437. He then returns to the pit lane.
@rizwan: Maybe not today, but at some stage over the next four days the teams will attempt a race simulation and that should give a clearer picture of where they all stand.
Only Sainz out on track curently.
@GoldenOldie: Indeed, I was waiting for a picture to come through.
@hymogue: Massa was on hards, Hamilton on mediums.
Lots of cars running with aero sensors on their cars today. Lotus has one on the rear wing, McLaren has something further down on the front of the car.
@Alan: Well that's the point of F1!
If you look closely at that Lotus, you'll see the road across the rear of the car. That will be to measure airflow from the back of the car.
@rizwan: They will not be able to compete in Melbourne if they have an unsafe car. The FIA is looking into the accident (as it does whenever a driver ends up in hospital) so if it's unsafe, we'll know quickly.
@mfbull: To have new aero parts every year. Innovate etc.
