The race had been halted due to a track blockage at the far end, and on the restart, a car hit one of the fence supports right in front of my camera. The impact seemed quite mild, but the driver did not get out of the car as usual and a medic ran up and climbed into the car. Another crash happened nearby and the race was stopped. The onsite medical and marshals were unable to remove the driver from the car and attempts to remove the roof failed. The fire service were called and an ambulance. The fire crew were able to quickly remove the roof of the vehicle and the driver was removed on a spinal board - the rescue taking nearly and hour. It started in daylight and was completed in artificial lighting.
The video clip starts with the crash itself, then friends of the driver stopped me shooting the rescue operation. The clips recommence as the rescue services are leaving. The end clip is the race before the restart. This clip shows the cars being flagged to a stop = shortly after this the crash happened.
Pure luck I was there, a simple handheld test of the camera to see how it coped with the falling light level and the transition to artificial.
No editing - bar just joining the clips together.
The question people are asking is how what looked like a gentle bump caused the injury that followed, when the green car that passed one circuit later managed to roll, and the driver was fine. Just goes to show - doesn't it?
