The 1969 British Grand Prix was a Formula One motor race held at the Silverstone Circuit on 19 July 1969.

It was race 6 of 11 in both the 1969 World Championship of Drivers and the 1969 International Cup for Formula One Manufacturers.

The race developed as a contest between Stewart and Jochen Rindt who constantly overtook each other by slipstreaming.

It was on one of these occasions towards the end when Stewart signalled to Rindt as he drew alongside[1] that the end plate of his rear wing had come loose and was fouling the left-rear tyre each time Rindt flung his Lotus through a fast right-hander.

However, his team failed to put enough fuel into the car to enable him to finish the race and consequently he was obliged to make a further stop.
