A number of European scientists were said to have gone with Marconi, including Landini. In 1937, the enigmatic Italian physicist and alchemist Fulcanelli warned European physicists of the grave dangers of atomic weapons and then mysteriously vanished a few years later. He is believed to have joined Marconi's secret group in South America. Ninety-eight scientists were said to have gone to South America where they built a city in an extinct volcanic crater in the southern jungles of Venezuela. In their secret city, financed by the great wealth they had created during their lives, they continued Marconi's work on solar energy, cosmic energy, and anti-gravity. Working secretly and apart from the world's nations, they built free-energy motors and ultimately discoid aircraft with a form of gyroscopic anti-gravity.

In the most incredible scenario so far, and one that may well be true, Tesla was induced to fake his own death, just as Marconi and many of the other scientists had done, and was taken, by special discoid craft, to Marconi's high-tech super-city. Away from the outside world, the military governments, the oil companies, the arms and aircraft manufacturers, Marconi and Tesla, both supposedly dead, continued their experiments in an atmosphere conducive to scientific achievement.

Yet a secret city in a jungle crater was the least of the claims. Genovese insisted that flights to the Moon and Mars were made in their flying saucers. He claimed that once the technology had been conquered, it was relatively simple to make the trip to the Moon (a few hours) or Mars (several days). Genovese does not mention pyramids or what they did on Mars. Perhaps they created a Martian base in one of the ancient, sand-blown pyramids of the Cydonia region.There have been many reports of UFOs in South America, especially along the edge of the mountainous jungles of the eastern Andes, from Bolivia to Venezuela. Is it possible that some of these UFOs are anti-gravity craft from the Ciudad Subterranea de los Andes?
