FIA race director Charlie Whiting admits he nearly brought the British GP to a halt after four drivers saw one of their rear tyres explode.
Lewis Hamilton, Felipe Massa, Jean-Eric Vergne and Sergio Perez all had their races stymied by left-rear tyre failures, with the quartet lucky to remain some semblance of control of their cars during the incidents.
With tyres puncturing with such regularity, concern for the safety of the drivers grew, and Whiting reveals that when Perez's tyre blew on lap 46, he considered red flagging the race.
"It was quite close to being red flagged. It did occur to me to do that," said Whiting.
"I don't want to put figures on it, but it was close," he added of how many punctures would have ended the race.
"I don't think we've seen anything like this (in F1 history). I can't remember anything. To have four total catastrophic failures, I believe, is a first."
