Now what I am about to post below...Is just thinking out loud for the most part. The scenarios are hypothetical only, and do not necessarily represent
my personal view on the subject...Now that you have been warned...
I would have to agree that this is technology, if it exists, is more than likely terrestrial in origin, instead of extra-terrestrial. The main reason
I say this is because in all of the credible accounts of UFOs that I have been told first-hand, the objects were usually very large, as well as
completely silent.
However, this is not to say that it is not possible for a craft such as this, if it exists, to produce such noises. Reason being, moving air and
creating sound waves are a physical phenomenon that cannot be bypassed without some type of advanced technology, and a craft that contained the
necessary mechanisms, design, etc, to become silent, may have been repairing their craft during the days and weeks that the sounds were being heard.
This however, would mean that it was the same craft, as I doubt multiple crafts would have the same failures all around the world. And if it was one
craft, wouldn't it have been fixed sooner? If that is too far-fetched, let us say that they did not put cloaking technology on the craft, if it
exists. I believe the accounts that have personally been related to me, describing the crafts as silent, are legitimate. With that said, if the
technology exists to stay hidden, and is used on other craft, then why not on this particular craft?
This leads me more to believe that our government, or some other country's government, is testing their new cloaking technology right under all the
noses of the world. This is, if the OP is correct.
