Throughout the entire three decades of crop circle phenomenon sightings of various craft, paranormal entities and most of all are these unexplained football sized Orbs. They tend to appear to the naked eye at first as a glint of bright light, almost as if someone is reflecting sunlight through a small mirror. If you spot something like this then concentrate your cameras to the sighting area.

There has been many instances where Military Helicopters have been seen searching / chasing these Orbs, but when they find them then a game of cat and mouse begins. Orbs sneakly appear in front of choppers then mysteriously disappear and the reappear behind the choppers. I would say due to the orbs ability to move at rapid speeds and capability to become invisible, it would be probably impossible to capture one.
