I think we are their now, but in the 60's, idk. I'm not saying for sure, I wasn't their. Yes I think we can, we are human and can do anything we put our heads to. I just read that article and don't think it would be possible bc they state between vibration, satellites, space crap, winds and so on it would never work. I think we could build it, but not maintain it at all. It's a toss up, there is amature audio I think on FM talking about aliens and shit, it would be awesome if we did make it. I like the videos that shows what appears to be alien ships following the us.
