THE PHILADELPHIA EXPERIMENT: In 1956 astronomer and UFOlogist Morris Jessup received an extraordinary letter. It claimed that during World War 2 the US Navy had experimented with invisibility and teleportation in a botched test on a destroyer, the USS Eldridge. Jessup's search for the truth will lead him to pay the ultimate price. APE-MAN ARMY: In the 1920s and 30s Soviet scientist Dr. Ilya Ivanov began a series of disturbing experiments to cross breed humans with apes. At first he tried to make female apes pregnant using humans as the fathers. His experiments grew so grotesque he was expelled from French Guinea in Africa when he attempted to make women pregnant using apes as the fathers. But his research continued in Russia. Did he succeed? ZAPPED TO DEATH: Thomas Edison was a great man, one of the inventors of the modern world. But even the greatest men make mistakes. Caught up in a commercial battle to supply America with electricity, Edison ran a disturbing publicity campaign against his bitter rival George Westinghouse. The campaign used Westinghouse technology to electrocute animals. Ultimately Edison's campaign went even further, leading to the invention of the electric chair. It was a battle Edison regretted for the rest of his life.
