There are many possible explanations for a semi-transparent appearance to an airborne object: 1) Low visibility paint - see US Navy aircraft paint schemes - or other sky-similar coloration 2) Luminous emissions from the near surface area of the object, with a color similar to the sky. 3) High reflectivity. 4) (1), (2) or (3) combined with haze. As long as an object does not pass in front of any object in the sky there is no way to determine transparency. In the case of (3) or (4) even apparent passage in front of a cloud or other object may not be suifficient, unless the field of view from the object toward the observer differs substantially and distinguishably from that behind - and even in that case, there can well be a number of unusual perceptual factors at work which might still convey the impression of transparency. ------ Mark Cashman, creator of The Temporal Doorway at http://www.temporaldoorway.com - Original digital art, writing, music and UFO research - UFO cases, analysis, classification systems, and more... http://www.temporaldoorway.com/ufo/index.htm ------
