British Grand Prix, Silverstone Free Practise

Ferrari's championship leader Felipe Massa crashed heavily but still set the fastest time in Friday's free practice for the British Grand Prix.

Massa, the first Brazilian to lead the Formula One standings since the late Ayrton Senna in 1993, skidded on oil deposited on the track by the Renault of double world champion Fernando Alonso.

The Ferrari spun at the 210kph Stowe corner, slamming backwards into the wall with 33 minutes of the first session remaining.

Massa stepped out unhurt but the car suffered considerable damage to the rear. The red flags came out as marshals removed the wreckage and cleared oil from the track during an 18-minute stoppage.

"It was a big crash, but that's part of the game and I have had much worse accidents in my career," said the Brazilian.
