É archaeologists have been
racking their brains over the geometric system of
lines, animal drawings and neatly arranged bits of
stone which extend over an area some 30 miles long
between Palpa in the north and Nazca in the
south. To me, they look just like
an airport layoutÉ (Gods from Outer Space, 115)
At some time in the past,
unknown intelligences landed on the uninhabited plain
near the present-day town of Nazca and built an
improvised airfield for their spacecraft which were to
operate in the vicinity of the earth. (Gods from Outer Space, 117)
