Always fascinated by the (fairly) recent black triangle reports. For decades we've seen the triangles -- and still do -- and then, newer reports of rectangular triangles. Are they of the same source? Is the latter a new, improved version of the first? Just different models but the same intent and origin? Private (and I use that term loosely, as in private-military-industrial-complex) or truly, literally, alien? I have no idea, but I tend to reluctantly lean (because I do love a good alien scenario) towards the human made shadow government explanation. Which, in many ways, is just as scary as aliens.
Note: what's also interesting about this report is that it was made by an astronomer. Take that
