The noisiest of sports fell silent at the British Grand Prix on Sunday as Formula One paid its respects to those who lost their lives in the London bomb blasts.
After the national anthem was played, drivers stood together, cap in hand for a minute's silence 10 minutes before the race.
The 100,000 sellout crowd joined them as a hush fell over the former World War Two airfield and flags flew at half mast.
"I think I speak on behalf of everyone involved in Formula One, that we are obviously deeply shocked and saddened by what has happened in London," BAR's Jenson Button said earlier in the week.
"My heart goes out to all the victims and the victims' families that have been involved."
Security has been stepped up at Silverstone after Thursday's blasts, with cars and bags searched at entrance points and police officers in the paddock.
More than 50 people were killed and over 700 injured when three bombs were set off on London Underground trains and a fourth blew up a double-decker bus.
