International motorsports chief Jean Todt has promised the governing FIA will investigate Sunday's horrific aerial crash at the Macau Formula Three Grand Prix which left 17-year-old German driver Sophia Floersch with a spinal fracture.
Floersch was catapulted off the track into a photographers' bunker after traveling at more than 275 kilometers per hour (171 mph) on the tight street circuit.
The teenager was from a former Portuguese colony from where he tweeted that he was "fine" and would undergo surgery on Monday.
"After the serious incident today in Macau the FIA is mobilized to help those involved and analyzing what happened," the International Motorsport Federation (FIA) president Todt tweeted.
"We will monitor the situation and make the necessary conclusions."
Japanese driver Sho Tsuboi, who was hit after the initial impact, was also taken to hospital complaining of back pain but the Macau Grand Prix Organizing Committee said he had been discharged after treatment.
