Jealous much? Don't be. I had to sacrifice my ears to the roaring engines at Silverstone last Friday, just for you lovely people. While the Formula One teams were taking a break from the Grand Prix practice sessions, I was able to sneak into the pit area and get up close to Vodafone McLaren Mercedes' shiny stallions -- no touching allowed, naturally, but I did learn a thing or two about their pre-race preparation. And to top things off, legendary driver Jenson Button also popped by to share some thoughts on McLaren's F-duct system (a cunning and legal trickery that lets the driver's left leg redirect airflow over the rear wing in order to stall the flap, thus reducing drag when doing straights), as well as a few grumbles about the sharp corners on the recently renovated circuit. Video's after the break, and be sure to crank up your speakers for maximum sensation.
