Havving examined the phenomenon of the crop circles, we can not overlook or purposely forget the abbundant testimony of unidentified flying objects,witnessed and photographed while they flew over these siites.It is obvious that a certain part of this testimony could be subject to opinion or could be an attempt to gain personal attention or contaminated by the interests and intents of the same witnesses;that however can't be dennied before hand.
Other witnesses have claimed to have seen glowing orbs of various dimensions move in circular patterns above these crop circles.Others still claim that this strange symbol in the field formed after many of thier excursions.
A renound video tape of the glowing orbs that create a crop circle exists. On August 11,1995 at 5 am.,at Oliver Castle,some small glowing orbs were taped while they flied over a field,instantly leaving an engraved drawing in the grain field below.
The video was realized on an analogic support and thus could not be an apparent trick,that could be done with a digital camera.
There is much debate about this issue. On one side there is an ensamble of research laboratories that claim tthat the recording is real,on the other side the same number of labs say that it is a false.
