Here’s the original presentation of the video used on Fact or Faked as presented at the 2008 MUFON Symposium in San José (July 2008). Watch closely to all the footage. There does appear to be a “head” which I was not able to see on Fact or Faked.
Watch what appeared to be moving legs in the television broadcast. It does look like fabric of sorts that is catching the light. Check the shadow.. there is no separation as the “legs” move.
