UFOTV Presents: Ancient Advanced Technology - Peru & Bolivia

David Hatcher Childress (Ancient Aliens the Series) flies to Peru with British engineer Christopher Dunn. Together they journey to Cuzco in the Andes Mountains to examine evidence for the possible use of advanced rock-machining techniques. They again examine saw marks, advanced lifting and moving techniques, as well as evidence of Pre-Incan megalith builders at Machu Picchu and Ollantaytambo.
