Guess it's time to weigh in:
First and foremost, congrats to Ric and company for continuing the search. I can only imagine how stressful and frustrating it must have been spending hour after hour watching video of "nothing discernable" punctuated by periods of trying to free stuck or malfunctioning gear. My hat is off to the guys that can do this sort of thing and still maintain a degree of optimism.
Having said all that, I'm afraid I have to side with the "face on Mars" crowd (though "Bihimini Blocks" might be more appropriate in this situation). While I suppose one might be able to argue that certain portions of this still show man made artifacts (and please note the "might"), I see nothing that screams "Plane!". Fortunately, the question isn't what "I" can see. I have no credentials as a photo interpreter of any sort so we'll just have to wait for the experts to weigh in on that one.
Sorry I didn't get to see the Discovery special but we don't have cable access where I live and I don't watch enough TV to make satellite, etc. worth the money. I'm hoping I'll be able to catch it when it is released online.
Keep the faith,
William
