One possible theory is that they aren't massive objects at all but instead are some sort of 3D projection in the air, probably involving plasma produced with high powered lasers, RF beams or particle beams. That would require technology that isn't publicly known but probably doesn't violate any laws of physics. However if you believe the claims made in this article that high-ranking officials have excluded the possibility that the events were due to any US SAP then this possibility becomes more remote. I think if anyone on Earth has this technology it would be the US, simply because they spend so much more on defense than any other country.

Interesting that there is a good amount of circumstantial evidence that leads this way. I saw the phenomenon with other witnesses as well 22 years ago and I simply cannot rule out projections. Seems simple enough and able to explain it all. But then again there is supposed to be physical evidence which would contradict everything I just said. Now that would be something.
