On November 22, 1963, in Dallas, President John F. Kennedy was assassinated. Photographers took many pictures that day at the scene of the crime, some showing a mysterious woman holding a camera. The unknown woman was nicknamed Babushka Lady because she wore a headscarf like elderly Russian women.

In June 1908, a massive explosion occurred near the Stony Tunguska River in Russia. The blast leveled 770 square miles of forest, uprooting approximately 80 million trees, yet resulted in no loss of life. It has been theorized that the Tunguska event, as it came to be known, was caused by an explosive meteoroid, but no one knows for sure. There was no impact crater, so the conjecture is simply that it broke up in the atmosphere somewhere between three and six miles above the Earth's surface. The explosion is estimated to have been 1,000 times more powerful than the atomic bomb dropped on Hiroshima, Japan.
