They are shaped like an actual cigar, roughly 2000 feet long. Saucers have been seen dropping out of them and those metallic spheres you see come out of saucers and are essentialy drones for collecting data and intervening in anything it deems damaging to the planet. The metallic spheres have been seen collecting water, stopping rockets and also they are responsible for crop circles as they use microwave beams to flatten the wheat. I know that sounds like a bold statement but I've been reasearching this for a very long time.
secondly the objects seen hovering over crop circles are often reported as being balls of light or pure energy instead of metallic spheres or something necessarily solid, although I suppose they could be solid but just are very bright. This presentation by Pierre Beake shows some great rarely seen footage of balls of light seen over crop formations (skip to 58:13)
Hey timeisart I would love to, I typically refrain from calling them orbs because that suggests they are of pure energy not something of solid matter. I have seen them create crop circles in their metallic state. But yes they have been seen glowing bright orange amongst other Color’s and I feel that this is a byproduct of their technology and not their natural state but that’s just one man’s opinion and I would love to discuss this with you further to hear your thoughts.
