And another thing about the 70's - Erich von Daniken!  Remember him?  Chariots of Fire was all over the place!  You couldn't get away from aliens.  They were everywhere, abducting people and putting probes into them.  I think even cornball shows like Mike Douglas had guests that claimed to have been abducted by aliens.  The Sighting is very consistent with what was going on back in the mid-70's.  Anyone who disagrees must be young and wasn't aware during that era.
