Are UFO's ether ships? Believe it or not I found this cartoon caption on a UFO website. The UFOlogist was referring to Steiner's insights into the etheric realm and etheric forces as explaining the power source for UFO's.

Constable came to believe that his (UFO) photographs showed 'aerial fauna' - conscious'bioforms' of etheric energy of the sort believed in by followers of Rudolf Steiner.
