International motor racing boss Jean Todt has promised an investigation into the terrible aerial crash at the Macau Formula 3 Grand Prix, which left the German driver Sophia Floersch, 17, with a fractured spine.
Floersch was catapulted off the road into a bunker of photographers after crashing into the back of a car and overtaking another as he traveled more than 275 miles an hour on the tight street circuit.
The teenager was aware when she was taken to the hospital and later tweeted that she was "well" and would undergo surgery on Monday.
"After the serious incident in Macau today, the FIA is mobilized to help those involved and analyze what happened," said Todt, president of the International Automobile Federation (FIA).
"We will monitor the situation and draw the necessary conclusions."
Japanese driver Sho Tsuboi, who hit Floersch after the initial crash, was also taken to the hospital complaining of back pain, but the Macau Grand Prix organizing committee said he had been discharged after the treatment.
Medical director of the event, Dr. Chan Wai Sin, said two photographers and a track marshal were also injured in the accident and were taken to the hospital for treatment.
Floersch is competing in his first season in the junior F3 series. She was in 15th place when the crash happened on the fourth lap.
The German Mick Schumacher, son of the great Michael Schumacher, who participated in the race, tweeted: "Our thoughts are with (a) SophiaFloersch and the other wounded, we look forward to the best. (Hashtag) StayStrongSophia".
According to Chinese driver Guan Yu Zhou, who was driving behind Floersch, there were yellow warning lamps on the track just before the accident, which he said appeared to be "an organizational mistake."
"Sophia was very close to Jehan Daruvala, and when she stopped early, she did not have time to react," he said.
The falls are frequent at the Macau Grand Prix, which this year, in its 65th edition, hosted six car and motorcycle races in the 6.2 km of Guia Circuit through the streets of the island.
Last year, British motorcyclist Daniel Hegarty died after crashing the security barrier during a race, the eighth driver to have lost his life on the circuit since 1973.
Three motorcyclists were rushed to hospital after crashes at the circuit this week with Britain's Andrew Dudgeon demanding that a metal rod be inserted into his spine after an accident in practice.
Dudgeon comes from the Isle of Man in Britain, where 270 motorcyclists have died in competitions on the island's TT circuits for the last 120 years.
