I took a look at the link and these are the clearest photos I have ever seen of any UFO.

The person who took the photos mentions that the craft moved as though in an 'insect' way. My immediate thoughts when I saw the craft were of an insect as well, like one of those very thin bodied, long legged spiders.

I somehow find it odd to see 'manufacturing' markings on the under surface of the blades.

This looks to me like a mixture of alien/human technology.

Exactly what this device/craft is used for, one can only speculate.
