I have just watched a dvd which goes into great depths about the
formations of crop circles and its blown my mind away. Now only are
the formations in crops, but sand, and ice and snow. It has been
proved that they are not man made because of the way the cells in the
plants are altered somehow in the first 15 seconds of formation, to
make them supple for bending, then they are hardened again. A
military operation (practice) was being carried out in the uk and a
helicoptor passed over a formation and took photographs of it. Upon
its return 7 hours later, the same helicoptor took more photographs.
Amazingly, looking at the first photos, the crops were laid
clockwise, yet the photos from the return flight showed them now as
anti-clockwise. They had been re-laid.
