The low effort comments on this topic is surprising, considering that this community has many experts in respective scientific fields. There is not much effort to bring deep legal/scientific critical analysis into the subject. Even if this is an extraordinary claim, that it is backed by so many professional witnesses should warrant sincere investigation rather than banter and ridicule.
HackerNews can be skeptical in interesting, informative ways - the discussion from yesterday of how the superconductor video could have been faked or could be representing something other than a superconductor is a great example. The UFO discussions are usually not that.
