Floersch is scheduled for surgery Monday.
She then sped backwards towards the turn and after clipping the kerb, her auto became airborne before she hit fellow driver Sho Tsuboi at incredible speed.
Videos capturing the moment when a Formula 3 vehicle lost control and flew through the air before crashing into a fence at the Macau Grand Prix, which took place from November 15 to 18 at Macau's Guia Circuit, have been circulating online today.
Fortunately, Floersch survived the frightful crash but has been diagnosed with a spinal fracture, to which she'll undergo surgery soon.
Everyone involved in the crash, including Floersch, Tsuboi, two photographers, and a marshal, was rushed to the hospital following the incident.
According to the Motosport.com report, Floersch rear-ended the then-15th placer Jehan Daruvala on a flat-out part of the track, which put her out of control onto TOM'S Dallara-Toyota of Sho Tsuboi. She's okay, although she did fracture her spine.
The driver of the other auto, Sho Tsuboi, also crashed and was taken to hospital, as were two photographers and a race marshal.
Media reports said Tsuboi has lumbar pain. Both are being observed in hospital. "The surgery that began this morning continues".
