On June 30th, 1908, a mysterious explosion shook the remote Siberian region of Tunguska. The blast flattened 80 million trees across 800 square miles.
Every plant, every animal, every insect in the blast radius was vaporized. The shockwave was felt as far away as England.
It looked like a comet impact, yet, no crater was found and no debris was discovered. Scientists still can't explain what happened.
But... at that exact moment, on the other side of the world, Nikola Telsa was conducting his latest experiment: transmitting massive amounts of electricity through the atmosphere.
Tesla activated the generators in his lab and fired up Wardenclyffe Tower for one final, dramatic test: and sent millions of volts of electricity into the sky.
After the test was complete, Telsa looked at the readings on his equipment and said: "Oh no."
