On January 1. 2011 a couple of medical professionals on a trip to Peru, took the first early morning flight on a small Cesna aircraft to view the famous Nazca Lines. This video was taken from the plane window during the viewing of the lines.
The weather was absolutely perfect, as it usually is in this part of the desert. From out of no where, the plane was overtaken by a large dark dense set of clouds. The passengers described fear as the captain of the plane asked them to brace themselves against the immenent turbulance.
The small craft was soon entirely engulfed by the clouds. The man videoing the Nazca Lines kept the camera rolling as they passed through the clouds. Unknown to the tourist was the disk that passed unsafely close to the plane. He did not notice it until they returned to their room later on in the morning and viewed the tape.
He was so shocked at what he had seen that he uploaded segments of the flight and shared them to be viewed by others. At this time the tourist is still in Peru for another 10 days and will not be available for questions until he comes back to the US.
