They then viewed the massive sketches from the air. They did this both to aid in the creation of the picture as well as to appreciate their air. In 1977,Jim Woodman suggested that the Nazca people must have used aircraft—likely hot air ballons—to view the drawings from the air. Woodman and his team even constructed a ballon out of materials that would have been available to the Nazca people.
Other researchers suggest that the lines were not meant be viewed by humans.
