USGP: Alonso fastest in opening practice

McLaren's Fernando Alonso dominated the top of the time sheets, but BMW-Sauber's runners – including stand-in debutant Sebastian Vettel – also impressed after clocking the second and fourth best times.

Kimi Raikkonen and Felipe Massa were fifth and seventh in their Ferraris, while Renault's duo conspicuously lagged the pace; Heikki Kovalainen managing to better only Anthony Davidson and the two slowest Spykers.
