I have recently just watched an Unsolved Mysteries Documentary on UFO's I'm not to sure what year it was from so maybe this is old news! In this documentary they gave several reasons why some crop circles can simply not be hoaxes or be created by humans in anyway I have not heard any of these facts before so would be interested to know if anybody else has and maybe has info that disproves them!

1. The base of the crop whatever crop it maybe in a hoax is always broken on the section that enters the ground in the other type the base has been softened bent over and the re-hardened again and the crop continues to grow as normal and can still be harvested!

2. Using sound equipment there is a noticable interference recorded near the centre of one of the circles wich dissapates the further away from the centre you move!

3. A study has been done into the cellular structure of the crops comparing samples from inside the formation to those outside it. The samples taken from outside the formation had cloudy crystals in an erratic pattern and those from within the formation had clearer crystals in a much more uniformed pattern!

In the documentary it mentioned footage that had been captured of the formation of 2 crop circles by a team of scientist under the name operation blackbird I was wondering if anybody knew anything about this footage? It also mentioned formations that had appeared in the Arctic circle If anybody has any pics would be great to see them!
