In less than 24 hours after suffering an accident at the Road Atlanta track in Braselton, Georgia, the Nissan DeltaWing is back on track and ready to race in this Saturday's Petit Le Mans event - the final round of the 2012 American Le Mans Series.The accident happened when the Nissan DeltaWing was struck in the left rear by a GTC class Porsche just as driver Gunner Jeannette came under a bridge. There was damage to the car from the subsequent rollover and impact with the wall that had the Nissan DeltaWing team working throughout the night to rebuild the car. Jeannette walked away from the accident unscathed, thanks to the car's "tub" - a carbon-fibre survival-cell used in all Le Mans-style prototype racing.
