Das Rätsel von Tunguska plot
What happened in the Siberian taiga on June 30, 1908? It was probably the largest explosion in human history to hit the Tunguska region of Siberia on the morning of June 30, 1908. With a force of more than a thousand atomic bombs dropped on Hiroshima, a forest area the size of Saarland is destroyed within an hour. One hundred years after the mysterious bang, German geologist Christoph Brenneisen sets out on an expedition to the impact area. He finally wants to solve the riddle, because a crater or other convincing piece of evidence for the cause is still missing.
