>With rockets, well, we already had rockets. The author uses naivety, but this statement is very questionable to anyone interested in spaceflight. No, "we" didn't have any vertically landing reusable rocket capable of autonomous reentry, except one primitive atmospheric demo vehicle with manual primary controls. Let alone engines such as Raptors in the western world. Anyhow, the presentation itself didn't seem to take itself very seriously, so I wouldn't think too much about the (very difficult) feasibleness of this, they must be aware. Hell, it may just be an elaborate advertisement for jobs.
