99 Luftballons?
Strangely, the cause of the power outage that affected over 35% of the area and over 300,000 homes and businesses, was a metalized balloon that drifted into a 110KV substation and tripped the system, shutting down power across the area. The police are investigating the source of the balloon and whether it was radio controlled, however while it was recovered, it was quite burned. If any control systems are found it would be considered an ‘attack’ rather than an unusual accident.
