In the 1960s at a high-voltage test facility in Siberia, a 90-foot tall Marx generator producing 5 million volts produced super long discharges that traveled hundreds of meters across an open field, crossing from the tower top to hit transmission lines and streetlights in a parking lot, despite classical theory predicting arcs should only reach about 2.5 kilometers at 2,000 kV/m but instead reached with less than 100 kV/m, only a twentieth of normal requirements.
