Fernando Alonso topped the timing screens at the end of the first free practice session of the United States Grand Prix weekend, at Circuit of the Americas in Austin, Texas.

Fernando_Alonso-FerrariDense fog caused a half hour delay to the start of proceedings, and when they finally got underway the running was brief before the red flag waved to stop the action, because the medical helicopter was not at the venue for some odd reason the result was that what should have been a typical 90 session was truncated to around half an hour.

Alonso, who was nursing a back injury, set the session best in the opening laps, but it quickly became apparent that the likes of Red Bull, Mercedes and Lotus were not trying to go for hot laps in the limited remaining time.
