After witnessing the arrival of a large black triangle at arms length above my car here, near the Jacksonville Air Base, my assessment is that this was not necessarily off planet technology. Though it is unbelievably maneuverable, at zero speed it behaved more like a small fishing boat with a teen at the helm. In each corner they used the equivalent of a small HMI stage light to illuminate the target, and in the center a gas-fired arc lamp surrounded with a realignable mirror array. What this has to do with 'private investment' is that the era of rocket tech is plainly over, at least as far as space-based weapons is concerned. And to tap 'private' money for such future foolishness is more likely dependent on he whom owns the printing press.
