This may surprise you, but no one is assembled to deal with your crop-circle alien fantasies. Almost everyone here has come for the amusement value of these harmless pranks. And also to see yet another example of what some folks will grab onto ... UFOs, Bermuda Triangle, pyramid power, ancient astronauts, astrology, magic crystals, channeling ... now it's silly shapes in the broccoli fields.
Your crew IS checking in, and yes, you and they DO arrive in an attempt to debunk certain phenonemon, crop circles amongst others.
Additionally, they aren't fantasies if they exist.
