I live a mile or two from the main gate of Aberdeen Proving Ground. I expect that I’ll see the blimp often. Course, we see lots if weird stuff and hear lots of loud booms.
I know many people who work in research there. None of them bear the demonic personalities the conspiracy nuts claim. Mainly patriots serving their country. Some are brilliant engineers, mathematicians and scientists who could make plenty in the private sector.
I suspect that if this test is successful that more will appear up and down the east and west coast. Former Army coast defense forts that have been inactive since WW2 will be taken back from State/private control.
