I have to confess the ufo serpents fasinate me. the strange worm like ufo seams to be alive as one, yet seperate and part of something bigger.
The ancient Maya believed that snakes could fly while china called them dragons, they have come to being known as sky serpents which seam to link with UFOs. Others would argue they are simply wind turbines revolve with the help of rotors which generates energy, that has somehow reached a great height in the sky.
Whatever they are really remains a mystery that we can only enjoy speculating :)
