Yes, it is. Paul Di Resta should have been in Formula 1 about the same time that Lewis Hamilton entered, but things took a slightly different route for Di Resta. Instead of keep doing the expensive single seater career move of going to GP2 after taking the F3 Euro Series championship Di Resta was taken under the wings by Mercedes and ended up in DTM (the German “Touring Car” series) in 2007. Not a bad move for Di Resta as he got to race for a large manufacturer in a high profile series, but it did leave him a bit out of the F1 race seat world eventhough he was with Mercedes.

For the last two year he has been a test driver for Force India F1 Team, which uses Mercedes engines, and the rumour mill now says that Force India are looking to promote him to a race seat next year with both Vitantonio Liuzzi and Adrian Sutil being question marks for 2011.

Only time will tell.

Jarno Trulli:
“I can’t say how disappointed I am to finish third but have the result questioned,” he said. “When the safety car came out towards the end of the race Lewis passed me but soon after he suddenly slowed down and pulled over to the side of the road. I thought he had a problem so I overtook him as there was nothing else I could do.”

But then earlier today the stewards decided to re-investigate the incident.

And the Stewards decision is now that Lewis Hamilton and McLaren have been disqualified. It appears that Hamilton in the hearing after the race told the Stewards that he had not been instructed by the team to let Trulli by. The problem is he had already told the media that McLaren had instructed him to let Trulli pass and furthermore the Stewards now have access to some pretty vital evidence; the radio communications.

At the FIA website it is now possible to listen to both the interview Lewis Hamilton gave to the media as well as the actual radio transmission between Lewis Hamilton and the team.

Edit:
Here are the radio communications between Jarno Trulli and his crew during the incident.

“I feel very happy to have come to an agreement with ART, to compete in this series,” he said. “I will put all my effort and dedication to obtain the best possible results with a lot of enthusiasm.”

The seventeen year old Mexican has a very impressive track record in his short career with a second place in the U.S. Formula BMW championship in 2007 followed by the European win in 2008. He started from pole position in the World Final, but ended third. He also made guest appearances in both International Formula Master (where he finished third at Imola) and in the German Formula 3 championship.

ART Grand Prix (formerly ASM Formule 3) has won the Formula 3 Euro Series in the last five years with Nicolas Hülkenberg (2008), Romain Grosjean (2007), Paul Di Resta (2006), Lewis Hamilton (2005) and Jamie Green (2004)
