No, I hadn't seen the thread, but I've heard the story. I started to answer this there, but thought better of it.

This story is more proof of human attempts to come up with this type of craft, before they realized how unstable the shape is. Was that what you were driving at? That most UFOs are examples of top secret military craft? If so, I'm not sure how much it would apply to the discussion here, but it would make the proper point when taken in context. A ton of research abounds in this arena, and most of it has been in relation to military application. That is food for thought.
