  18. Bull, people have survived being in the general vicinity of a lightning strike,
  19. anyone struck directly would be instantly vaporized. The breakdown voltage of
  20. air is 10,000V/cm, so 6ft above the ground the voltage of a lightning strike
  21. would still be 1.8e6 Volts, and being very nearly a true impulse, contains
  22. energy across the entire frequency spectrum.
