Red Bull Racing's Sebastian Vettel and Mark Webber dominated Friday's second free practice session for the United States Grand Prix on Friday au Circuit of the Americas.
However, it was Ferrari's Fernando Alonso who emerged fastest in the shortened first free practice session.
First fog and then problems with the trackside medical helicopter were to blame, causing a 40-minute delay. The cars took to the track for just 15 minutes before the session was red flagged, this time as a replacement helicopter was found. Eventually, the session resumed for 45 minutes.

The Spaniard two-time world champion was sporting visible strapping during the session, a consequence of his back injury he suffered in Abu Dhabi.
