Members of Team PrISUm were diligently working on their solar car’s battery system when lightning struck nearby.
It was the eve of the May 31-June 5 Formula Sun Grand Prix at the Motorsport Ranch in Cresson, Texas. The team had spent two weeks repairing and upgrading the car’s battery pack and brakes. The race’s technical inspections had all gone well. The team was making pre-race adjustments to the car’s battery system.
