Like SpaceX. However, when people gush about reusability, they seem to forget the 135 Space Shuttle missions (2 fatal failures , yes.). All done with 5 vehicles. Yes expensive etc, but truly amazing.
The Space Shuttle was a marvel of engineering. But while it was reusable, it wasn't actually good at it. Reusability was supposed to bring down cost and turnaround time and it did neither. And not just that, it was actually much more expensive than competing expendable rockets. Plus, it had lots of other issues like being dangerous as fuck. You couldn't abort at all for major parts of the ascent and there was the whole issue with the fragile heat protection tiles, both of which caused fatalities.
I think part of the reason why people aren't impressed by the Shuttle anymore is because it flew 135 missions. It's 40 year old technology. And it's not like SpaceX are just doing the same thing again 40 years later, they're reusing their rockets in a completely different way, which no one else had done before. And in doing so they seem to be avoiding most of the disadvantages that came with the Shuttle's design.
Also, I really don’t find anything SpaceX is doing revolutionary. Impressive? Yes, but it’s essentially incremental engineering, made possible by ginormous funding, including NASA money, and a private company doing things that NASA can-t politically afford.
Sure, I wouldn't say that no one else could do this with a similar amount of money (and the will to actually do it). Whether you want to call it revolutionary or not is subjective, but they're definitely innovating a lot more than any other large player in spaceflight. The Falcon 9 is a huge step forward for rocket reusability and SpaceX have also been the first to fly a full-flow staged combustion engine as well as the most powerful rocket ever. They're making spaceflight exciting again after like 40 years of stagnation and I think that's what resonates with people.
The Silmarillion is one of my favourite books, but I totally get this. Unless you’re really into Tolkien’s world as well as this style of book it’s not a fun read.
