Fan footage has emerged of Formula One driver Jules Bianchi's tragic crash at the Japanese Grand Prix on Sunday.

The short clip shows his car smashing into a recovery tractor, which had been deployed to remove a car that had crashed earlier. The 25-year-old Marussia driver's car had aquaplaned off the wet Suzuka track.

The unconscious Frenchman was removed from the wreckage and sent to a Yokkaichi hospital, where he is in a critical but stable condition. His parents Philippe and Christine arrived at his bedside on Monday. The International Automobile Federation (FIA), F1's governing body, said Bianchi had suffered a "severe head injury".

Drivers have pointed to the poor light being a factor in the accident, with some observers suggesting that the race should have started earlier in the day to avoid torrential rain ahead of the arrival of Typhoon Phanfone.

Williams team performance chief Rob Smedley said that the race was "the darkest I've ever seen a race event", while fellow driver Felipe Massa said conditions had been bad.

"I was already screaming on the radio five laps before the safety car that there was too much water on the track, but they took a bit too long and it was dangerous. So we saw that there were some crashes at the end," said Massa.
