“if they are earth based it means some other country has developed flying objects far beyond our known science”
A) These “flying objects” might not necessarily even be “flying objects” in the literal sense. Holograms, or plasma phenomenon, could create the appearance of objects that aren’t actually anything solid, which would explain why they don’t seem bound by the laws of inertia or gravity.
B) Just because the Navy says they’re not ours doesn’t mean they’re not ours. Classified stuff is compartmentalized and the Navy may not know about some projects.
There was an SCI project I was peripherally involved in supporting a lifetime ago. Had I met and told any of the people on this forum about it back then you would have all insisted that I was a nut that spent too much time reading ridiculous novels. Much of that specific thing is declassified now but its not as though the DoD sends you a letter telling you that you can start talking about anything so I don't. The thing is, I know that now you all know about this particular thing. Were I able to point it out you would tell me that anyone could have guessed that it was military in origin which suggests I don't know nuthin. It was the great (great? great?) grandparent to an unclassified tool that many of you use on a daily basis. If I were to spill the beans to someone now they would just assume Im making up stories to somehow aggrandize myself as though I was involved in inventing it when anyone can pull up the wiki page and clearly see who the "real" inventor was and its recent date of invention. Again, I wind up just being a nut so why would I say anything to anyone in the first place?
Sorry, distracted by an important call. The point of my post is that we all know that there are secret projects but society, including most FReepers, is not willing to accept the possibilities until its in front of them and then its just old news.
