> none of its boosters were reusable

Notably, they were reusable! Sure, they had to refurbish them, same with the shuttle’s main engines. The only thing they threw away was the external tank which didn’t have any engines.

Yeah this guy is smoking something. I actually think the shuttle landings were more impressive than this one. Not taking anything away from what they're doing here, but they're still only up to the mid-1970s technology-wise.
