Will confess I skipped the second video because it's the same dope who is already debunked. Manning (third video) agrees it's very possible. The video I linked directly addresses his concerns. I also agree with Scott that the largest viability hurdle is funding and finally economics of sustained launches. I believe we're back to my original comment. > Does this mean they can pull it off? I dunno. But what I've seen of the debunking videos (now and in the past), the debunking videos have themselves been debunked. Manning, who is generally well informed, agrees with my position. Frankly, I would ignore the first two videos. He's a dope who posts silly stuff to talk about. I've watched him before on other stuff. For some topics that's fine. But here, he's pretty silly and debunks himself. Anyone coming into the thread, I wouldn't waste my time on the first two videos. Edit: So no, not debunked. The debunking videos are themselves debunked. Scott seems to agree.
