This UFO with plasma from the propulsion system being ejected in vortex fields. Photographed over Casa Grande Arizona on September 14th, 2008. The UFO itself is not visible. For safety's sake I will refer to these objects as orbs, though they clearly are mechanical in nature and exhibit an intelligence that is in control. Photographed with infrared camera.
