'My heart really sank' - Hamilton relieved mechanic unhurt after hit

Lewis Hamilton says his "heart really sank" when his Ferrari car hit a mechanic in a pit stop in an incident that saw the team fined heavily by Belgian Grand Prix stewards.

Hamilton's right-front tyre struck the mechanic after the driver was given the green signal to leave the team's pit box, briefly knocking the crew member - who was in front of the wheel in an attempt to make a front-wing adjustment - to his knees. Hamilton promptly stopped his car as the mechanic, who was unhurt, was helped to his feet.
